test: make button-paints-content render check theme-robust
The render_pixels button test rendered on a black canvas and asserted some pixel differed from black. With no theme dir configured the active theme is the embedded B/W fallback, whose Light mode defines accent (the button fill) and text-primary as pure black on a white page — so a fallback button is black-on-black and the assertion spuriously failed. Render on white instead: the black fallback button stands out, and a real theme's saturated accent also differs from white, keeping the structural check theme-independent. |

touch: treat a compositor re-grab down as a drag continuation
When the surface that owns a touch drag is destroyed mid-gesture, the compositor re-opens the touch grab by issuing a fresh `down` on the surface now under the finger (smithay pins touch focus at `down` and won't re-target on motion). That `down` arrives for a slot the main surface already holds as its primary, with the drag state already migrated here. Handling it through the normal `down` path would either restart the gesture or, since the slot is taken, demote it to an auxiliary touch — both abandon the in-flight drag. `TouchHandler::down` now early-returns when the focused surface's `primary_touch_id` already equals the incoming slot, so the redundant `down` is a no-op and the following motion/up keep driving the migrated drag. Completes the cross-surface drag fix whose other half (migrating `primary_touch_id` on overlay teardown) already landed. |

windows: centralise input focus on a single FocusTarget, raise+focus on every window interaction
Focus was scattered across three stores — `Layouts::focus`, `Layers::focus` and `Windows::activated` — plus a hack that smuggled X11 surfaces through `Layers::focus`, with the keyboard target derived each frame from a `layers.focus.or(layout)` precedence. As a result "focused", "activated" and "has the keyboard" could drift apart: a window could be raised without taking the keyboard, the recurring "click a console window, then click it again before you can actually type" symptom.
New `windows/focus.rs` with `FocusTarget { Layout(Weak<Window>), Layer(WlSurface, app_id), X11(WlSurface) }`. `Windows` now holds one `focus_target: Option<FocusTarget>` as the single source of truth; `activated` survives only as a reconciliation cache for the xdg `Activated` state and is never set by hand. `set_focus` takes one `Option<FocusTarget>` and is the only entry point for changing focus: it brings the target to the front (`z_promote` + desktop stacking), refreshes the MRU and stores the target, and keyboard focus plus activation are applied from it on the next `focus()`. `focus()` resolves a baseline (the active layout's window, which carries `Activated`) and an overlay (a focused layer/X11 surface that takes the keyboard over the baseline without de-activating it), mirroring the old precedence but from one field, so keyboard focus follows focus by construction. `Layers::focus` is removed and X11 no longer rides inside it; the exclusive-keyboard layer path and `reap_layer` drive `focus_target` directly, and every click/touch/activation site collapses to `set_focus(Some(FocusTarget::…))`.
surface_at popup tie-break. When a layout hit is a popup or subsurface, its `wl_surface` is not tracked in `toplevel_z_order`, so the layout-vs-X11 z compare resolved to `None` and the X window underneath wrongly won — clicking a GTK menu (e.g. Firefox's) over an X11 window pressed the X window instead of the menu item. The tie-break now compares the owning toplevel's root z, taken from the hit's `FocusTarget::Layout` weak, so the popup's parent stacking decides.
Raise and focus on every window interaction, matching standard desktop behaviour. Client-driven (un)maximize, the SSD maximize/minimize/close buttons and the maximize keybind now bring the window to the front in both the render z-order and the hit-test stacking through a new `raise_toplevel` helper; previously only the stacking was updated, so an unmaximised window could stay visually behind another. Starting a move or resize — including a press on the resize edge — now routes through `set_focus`, so the window comes to the front and takes the keyboard before the drag instead of being resized or moved while it stays behind.
Input robustness around grabs and drags. A press under an active pointer grab (Wayland popup, drag-and-drop or explicit client grab) is routed to the grab instead of forge's own surface_at handling, so a click cannot leak to a window underneath a grabbing popup and a click outside the popup dismisses it cleanly. Only the press is blocked, never the release, so an in-flight move/resize drag or topbar swipe always reaches its end handler and can never stay glued to the cursor if a grab appears mid-gesture. `on_touch_up` now ends any active move/resize drag before its other early-return paths (armed SSD button, topbar swipe, app switcher) and drops a stale armed button, fixing a race where pressing a second, overlapping window left the drag running forever after release.
fix(input): keep the primary touch slot when migrating a drag across surfaces
A touch drag started on an overlay that hides mid-gesture (e.g. the app launcher when dropping an icon onto the dock or the homescreen) froze: it neither moved nor dropped. Destroying the origin surface migrated the drag state (long_press_fired / long_press_origin) and touch_focus to the main surface, but not its primary_touch_id; subsequent touch motion/up events then fell through the auxiliary path and never reached the gesture machine, leaving on_drag_move and on_drop uncalled.
reconcile_overlays and discard_overlay now adopt the destroyed overlay's primary_touch_id when a drag is in flight, so the rest of the touch sequence keeps driving the main surface. Touch-only; the mouse already migrated correctly via pointer_focus.
ltk: add a chassis module for full-screen ambient surfaces
New `src/chassis.rs`, re-exported from the crate root, gathers the scaffolding that every full-screen ambient surface — greeter, lock screen, kiosk — otherwise repeats by hand over the existing theme and `WallpaperBundle` primitives. `set_default_theme(mode)` finds, installs and activates the `default` theme document, returning the failure message instead of exiting so the caller decides how to abort. `theme_logo_rgba(size)` decodes the active theme's horizontal logo to RGBA, and `theme_icon_tinted(name, size, tint)` loads a symbolic theme icon and tints it. `branding_bundle_or_solid(name)` resolves a theme branding image (`"wallpaper"`, `"lockscreen"`, …) to a `WallpaperBundle`, falling back to a solid fill of the palette background when the theme ships none; `wallpaper_bundle_or_solid()` is the `"wallpaper"` convenience. `backdrop(content, &wallpaper, w, h)` stacks content over the wallpaper resolved for the surface size. No new capability — thin convenience over what the theme module and `WallpaperBundle` already expose — but it removes the per-application `load_theme_logo` / `build_wallpaper_bundle` / theme-bootstrap duplication.
ltk: animatable, input-transparent child surfaces via App::subsurfaces()
New `App::subsurfaces() -> Vec<SubsurfaceSpec<Msg>>` (default empty) describes input-transparent child surfaces composited over the main surface, with `SubsurfaceSpec { id, view, x, y, content_version }` and the stable `SubsurfaceId`. The motivating use is a slide/reveal that tracks a finger without the per-frame full-screen CPU re-raster a single-surface opacity or translate would cost: the content buffer is rasterised once and the compositor moves it.
`SubcompositorState` is bound in `event_loop/run.rs` from the compositor's `wl_compositor` (absent → `App::subsurfaces` silently degrades to none); `delegate_subcompositor!` is added on `AppData`, which gains a `subcompositor` binding and a `subsurfaces` map. New `event_loop/subsurface.rs` reconciles the live subsurfaces against the specs: each spec becomes a `wl_subsurface` sized to the main surface with an empty input region, so all pointer/touch falls through to the parent and the host keeps a single gesture/input model. The content — its own SHM pool and `Canvas`, drawn through the existing `DrawCtx` / `layout_and_draw` path — is rasterised only when the surface size or the spec's `content_version` changes; a position-only change emits `wl_subsurface.set_position` and commits the child surface, then a bare parent commit for placement. Committing the child is deliberate: desync subsurface state (the position) is applied on the child surface's own commit, not the parent's, so without it the move is queued but never lands. Positions are given in layout (physical) pixels and divided by the surface scale for the logical `set_position`.
The reconcile pass runs on every run-loop iteration rather than being gated behind a main-surface redraw, so a finger-driven move repositions at input-event rate, decoupled from the frame-callback cadence that paces full redraws — without this the subsurface only moved when the main surface happened to redraw, so a drag over a static background froze the panel in place.

ltk: responsive padding/spacing and scrolling, expanded theme palette, and bundled Adwaita cursors
A mixed pass over the default theme and the layout/input core, plus the toolkit's own cursor set. Grouped by area below. == Responsive sizing == Add `Length::dp( px )` — a "design pixel". It interprets `px` against a configurable reference vmin (default 412 px, the eydos mobile reference width) and returns `Vmin( px / reference * 100 ).clamp( px * 0.7, px * 1.5 )`, so a value authored against a mock-up scales with the surface without collapsing on tiny screens or ballooning on a 4K desktop. The reference is process-global, set via `set_design_reference()` and read via `design_reference()` (stored as f32 bits in an AtomicU32); both are re-exported from `lib.rs`. Make container and grid insets relative. `Container`'s four padding fields become `Length` instead of `f32`; every setter (`padding`, `padding_h`, `padding_v`, `padding_top`/`right`/`bottom`/`left`) now takes `impl Into<Length>`, so existing `f32` call sites keep compiling via the `From<f32>` shim. The values are resolved against the viewport in `Container::preferred_size` and in the container draw path (`draw/layout.rs`). `WrapGrid`'s `spacing_x`, `spacing_y` and `padding` get the same treatment, with a `resolved( canvas )` helper funnelling the per-frame resolution and `grid()` seeding `Length::px` defaults. Container tests now compare against `Length::px( … )`. == Scrolling == `Scroll::preferred_size` is now axis-aware. A horizontal-only scroll reports its child's natural height rather than claiming all remaining vertical space, so it no longer steals Y from its siblings when it sits inside a `Column`; vertical and both-axis scrolls keep the spacer-like `( max_width, 0.0 )`. `Column`'s space-distribution correspondingly treats a `Scroll` as a vertical space-claimer only when its axis allows Y. Disambiguate nested scroll viewports by direction. On press the gesture state now collects every scroll viewport under the point (`scroll_candidates`, innermost first) instead of committing to one; on the first 8 px of motion it locks onto the candidate whose axis matches the dominant direction (`scroll_locked`), so a horizontal scroller nested inside a vertical list no longer grabs the wrong axis. The pointer scroll hit test is aligned to the same innermost-first ordering. == Theme palette == `themes/default/theme.json` gains named colours (green / green-deep, yellow, orange / orange-deep, pink / pink-soft, sky-deep, error / error-soft, neutral-tertiary) and new semantic slots in both light and dark modes: `danger`, `text-tertiary`, `accept`, `chip` / `chip-active` / `chip-active-fg`, and `avatar-1` … `avatar-9`. == Cursors == Bundle GNOME's Adwaita cursor theme — the cursors GNOME Shell uses — into `themes/default/cursors/` so a Wayland compositor can draw consistent, complete pointers for ltk applications without the toolkit rasterising cursors itself and without depending on adwaita-icon-theme being installed on the target. The cursors are copied verbatim in XCursor binary format: 35 image files, one per CSS/freedesktop cursor name (default, text, pointer, *-resize, …), plus 27 customary X11 alias symlinks (arrow → default, hand2 → pointer, …); a sibling `cursor.theme` makes the tree a valid XCursor theme. The existing `ltk-theme-default.install` copies `themes/default` recursively, so the directory ships with no packaging change. Applications keep declaring a `CursorShape` per widget over `wp_cursor_shape_v1`; the compositor resolves it against the active theme's `cursors/` directory by name, and the set covers all 34 `CursorShape` variants. Document the set in `themes/default/cursors/README.md` (what it is, the XCursor layout, the full shape list, how the compositor consumes it, guidance for forks) and `themes/default/cursors/LICENSE.md` (attribution and licence options, modelled on the icons catalogue LICENSE). `lib.rs` lists the cursors in its third-party-assets section. Close out licensing in `debian/copyright`: a `Files: themes/default/cursors/*` paragraph records the upstream dual offer (CC-BY-SA-3.0 or LGPL-3, and CC-BY-SA-4.0 for the newer assets) attributed to the GNOME Project, with standalone CC-BY-SA-3.0, CC-BY-SA-4.0 and LGPL-3 paragraphs (summary-plus-canonical-URL for the CC licences, matching the existing CC-BY-4.0 entry; LGPL-3 referencing /usr/share/common-licenses/LGPL-3). The files are unmodified from upstream, so there is nothing to declare under the ShareAlike "indicate if changes were made" clause. Add `tests/cursor_assets.rs`: every `CursorShape` name resolves to a valid XCursor file (Xcur magic, following symlinks), `cursor.theme` is present, no entry is a dangling symlink, and the expected-name list stays in sync with the enum's 34 variants. |

text-input: re-sync on enter and flag secure fields as Password
LTK drives the on-screen keyboard through zwp_text_input_v3: focusing a text widget enables text-input so the compositor's input-method (squeekboard) brings the keyboard up. Two gaps are fixed here. Handle the `enter` event by re-emitting enable + content type + commit. The compositor sends `enter` when it (re)focuses the text input — notably when an input-method connects after the field has already enabled text-input (a startup race). LTK previously ignored `enter`, so that activation was lost and the keyboard never appeared; it now re-declares its state and the OSK comes up. Declare the content type from the field's `secure` flag: secure fields are flagged `ContentPurpose::Password` with `ContentHint::SensitiveData | HiddenText` (so the IME/OSK skips prediction, autocorrect and storing the value), everything else stays `Normal`/`None`. The content type is also refreshed when focus moves between two text fields (e.g. username → password) without re-creating the text-input object, and a new `AppData::text_input_secure` lets the `enter` re-emit path preserve the current field's type. Correct the docs: `TextEdit::secure()` and SECURITY.md claimed secure "skips text-input-v3 registration". It does not — the field still activates text-input so the OSK works on it; the protection is the Password / sensitive flagging, and the value still reaches a trusted compositor/IME. |

ltk: convert physical sizes to logical for overlays and input regions on HiDPI
Overlay `set_size` and input regions were handed physical (layout-space) pixels straight to layer-shell and `wl_region`, both of which expect logical coordinates. They only coincide at scale 1, so on a scale-2 output every overlay requested a surface twice its intended size and the input region covered the wrong area. `apply_input_region` now takes the surface scale and divides each `Rect` down to logical before adding it to the region; the four draw paths (software and gles, full and partial) forward their scale. `reconcile_overlays` converts `OverlaySpec::size` to logical for both `set_size` and the initial `OverlayConfig` (0 = fill survives the divide), and seeds the new surface's `scale_factor` from the parent so the first configure allocates a HiDPI buffer instead of rendering at scale 1 until `scale_factor_changed` lands a frame or two later. |

ltk: ext-session-lock-v1 client surface mode, plus a read-only mode for text fields
Add a third Wayland surface type to the runtime so an ltk `App` can be a screen locker, alongside the existing xdg-shell window and wlr-layer-shell surfaces. A new `ShellMode::SessionLock` makes `run()` bind `ext_session_lock_manager_v1` and request the lock at startup; the lock surface itself is created in the new `SessionLockHandler::locked` callback (one surface on the first advertised output) and replaces the `SurfaceKind::PendingLock` placeholder the main surface holds until the compositor grants the lock. The `configure` event routes through the same `on_configure` path as layer and xdg surfaces, so sizing and rendering are unchanged, and `finished` (the compositor denied or ended the lock) tears the loop down. The whole thing is additive and opt-in: the `Window` and `Layer` paths are untouched and nothing enters lock mode unless an `App` returns `ShellMode::SessionLock`, so existing apps are unaffected — the only non-additive edits are the two exhaustive `match`es on `SurfaceKind` (`wl_surface` / `try_wl_surface`), which gain arms for the two new variants. Doing the locker as a first-class surface rather than compositing a static texture into an offscreen `UiSurface` is the whole point: the compositor gives the lock surface keyboard focus, so ltk's existing text-input, editing, focus and IME machinery works inside the lock exactly as on any other surface — cursor, click-to-focus, Tab, character input. A locker built on top of this is just a normal interactive ltk app that happens to be presented on the lock layer, with no special input plumbing on the compositor or the app side. `App::requested_exit()` is the new way an app asks the runtime to tear the surface down and leave the loop; it is polled after every batch of `update`s. It exists because of the one hard invariant of `ext-session-lock-v1`: a locker that disconnects without sending `unlock` leaves the compositor's outputs blanked forever — that is the protocol's deliberate anti-bypass guarantee. So when `requested_exit()` returns true and the surface is a session lock, the loop calls `session_lock.unlock()` and round-trips the connection before setting `exit_requested`, lifting the lock cleanly; for a `Window` or `Layer` surface there is no lock and it simply exits. The consequence for lock apps is that they must stop calling `process::exit` from the lock path and instead flip a flag they return from `requested_exit()`. `text_edit` gains a `read_only( bool )` builder. A read-only field still renders its box and value in the normal field style but takes no keyboard focus and accepts no input: `Element::is_focusable` and `Element::is_text_input` now return false for a read-only `TextEdit`, which keeps it out of the Tab cycle, off the keyboard-edit path, and stops the cursor from ever being drawn on it. The flag is carried through `map_msg` so it survives `Element::map`. This is for presenting a known, non-editable value in the same visual idiom as the editable fields beside it — for example the already-known user shown on a session lock, where letting that field take focus or blink a cursor would be wrong. The `shell_mode()` doc comment and the README now list the `SessionLock` surface type and point at `requested_exit()` for the unlock. Two warnings are cleared along the way: the runtime no longer stores the `SessionLockState` after requesting the lock — it has no `Drop`, so the manager object outlives the dropped handle inside the connection and the lock lifecycle runs entirely off the returned `SessionLock`, which removes a never-read field — and a pre-existing rustdoc `private_intra_doc_links` warning in `list_item` (a public doc comment linking to the private `theme::ICON_SIZE`) is downgraded to plain code formatting. |

event_loop: drop the duplicate on_resize that clobbered physical dimensions with logical ones
Both `LayerShellHandler::configure` and `WindowHandler::configure` called `self.on_configure( w, h )` — which already forwards `app.on_resize( w * sf, h * sf )` in physical pixels — and then immediately called `self.app.on_resize( w, h )` again with the surface-local logical size. The second call won, so on any scale > 1 surface the app saw logical dimensions while the layout pass kept working in physical pixels. On a Librem 5 at scale 2 that meant `screen_width`/`screen_height` came through as 360×720 against a 720×1440 layout: homescreen icons rendered at half their intended footprint and the mobile wallpaper, sized explicitly via `.size( iw_at_h, sh )`, filled only the top half of the screen (the launcher / lockscreen / greeter use `.cover()` so they were unaffected). Remove the redundant `app.on_resize` from both handlers; `on_configure` is the single source of truth for the physical dimensions the app and the layout both expect. |

list_item: optional leading icon
Add a leading-icon slot to ListItem so settings-style rows can pair a 24 px symbolic glyph with the label. `.icon( rgba, w, h )` takes the same shape the rest of the toolkit uses for raw pixmaps; the draw path reserves `ICON_SIZE + ICON_GAP` on the left and shifts the label / subtitle text origin so existing icon-less rows render unchanged. |

ltk: introduce viewport-relative Length so any size, padding, spacing or font height can scale with the surface instead of being frozen at a px constant, fix text::preferred_size to honour the font-declared line gap, and add a responsive typographic scale
The motivating bug was a lockscreen in a downstream app (eydos-loginmanager) where the clock at 87 px overlapped the date at 24 px on a Pinephone but not on a winit dev screen. The root cause split in two: the layout was wired with a single `f32` spacing constant that worked at the dev resolution and broke at the smaller one, and `text::Text::preferred_size` was returning `ascent - descent` for the line height — fontdue's terminology for "the minimum bounding box of an unaccented line", which deliberately drops the `line_gap` that every typographic renderer (Pango, CoreText, DirectWrite) reserves between adjacent rows. At Sora's 200/em line gap, an 87 px row was visually 17 px taller than the rect the column allocated for it; stacked tight against the row above, the descenders bled into the row below. This commit fixes both halves at the toolkit level so every consumer benefits without bolting on a per-screen `Sizing` helper in their own view code. `types::Length` (with the `LengthBase` enum behind it) is the new currency for any "how big" or "how far apart" parameter. Six variants — `Px`, `Vw`, `Vh`, `Vmin`, `Vmax`, `Em` — cover the cases a real UI hits: absolute pixels for fixed-chrome decisions, viewport-relative percentages for sizes that have to survive a portrait/landscape rotation, and root-font-size multiples for typographic hierarchy. Optional `min_px` / `max_px` bounds attach to the same `Length` value via `.clamp( lo, hi )` (both ends), `.at_least( lo )` and `.at_most( hi )` (one-sided); the names are intentionally divergent from `f32::min`/`f32::max` to avoid being read with the opposite semantics (`x.min(24)` in std means "the smaller of x and 24", which is the inverse of what a min bound expresses). The bounds are stored as raw `f32` rather than nested `Length` values, which keeps `Length` `Copy` and avoids a `Box` allocation per widget per frame — the bounded-by-relative case (`Vmin(20).clamp(Vmin(10), Vmin(40))`) is rare enough that the trade is the right one. `From<f32>`, `From<i32>` and `From<u32>` are implemented so every legacy `.size( 24.0 )` / `.padding( 8.0 )` / `.spacing( 4.0 )` call keeps compiling unchanged; the migration is opt-in per call site. The `EM_BASE_DEFAULT = 16.0` constant matches `theme::typography::BODY` so `Length::em( 2.0 )` resolves consistently with the body-text default; a future change can thread a theme-supplied em base through without breaking the resolver shape. The resolver — `Length::resolve( viewport: ( f32, f32 ), em_base: f32 ) -> f32` — runs at layout time against a viewport supplied by the renderer. `Canvas::viewport_logical()` is the new helper that exposes that viewport: it divides the canvas's physical size by `dpi_scale` and falls back to physical size when `dpi_scale <= 0.0`, guarding the misconfigured-canvas path so a Vmin call doesn't poison every downstream measurement with `NaN` or `inf`. The viewport is in **logical** pixels — matching what every wayland `xdg_toplevel.configure` event already hands the client — so `Length::vmin( 18.0 )` on a 360×720-logical Librem 5 portrait surface resolves to 64.8 px and the same expression on a 1600×900 dev screen resolves to 162 px, automatically. Every widget setter that took an `f32` size, padding, spacing, max-width, or fixed dimension now takes `impl Into<Length>` and stores the value as `Length`: - `widget::text::Text::size( impl Into<Length> )`; the `size` field is now `Length`. `Text::resolved_size( &Canvas )` is the internal accessor that every measurement / drawing path routes through, so the field can stay `Length` without churning the call sites. `preferred_size` and `draw` now read `new_line_size = ascent - descent + line_gap` from fontdue's `LineMetrics` (the fix for the original bug) — the baseline placement is unchanged, only the row height grows by the font's declared leading, which is what every stacked layout was implicitly relying on. - `layout::Spacer::height( impl Into<Length> )` / `.width( impl Into<Length> )`; `fixed_height` / `fixed_width` are now `Option<Length>`. New `resolved_height( &Canvas )` / `resolved_width( &Canvas )` helpers replace the direct `s.fixed_height.unwrap_or( 0.0 )` reads in `layout::column`, `layout::row` and `layout::stack`. `Spacer::preferred_size` grows a `&Canvas` parameter for the same reason; `Element::preferred_size` passes the canvas through. - `layout::Column::spacing` / `.padding` / `.max_width`, `layout::Row::spacing` / `.padding` — all take `impl Into<Length>` and store `Length`. Internal `resolved_spacing( &Canvas )`, `resolved_padding( &Canvas )`, `resolved_max_width( &Canvas )` helpers funnel every read, so the layout code paths stay readable. The column's `inner_w` private helper picks up a `&Canvas` argument; the test that used it directly is updated. `theme::typography` keeps its historic `f32` constants (`H0`…`BODY_XS`, plus `LINE_HEIGHT`) so the migration is gradual, and adds a parallel responsive scale exposed as functions returning `Length`: `h0()`, `h1()`, `h2()`, `h3()`, `body()`, `body_s()`, `body_xs()`. Each is a `Length::vmin( pct ).clamp( min_px, max_px )` whose percentage is calibrated against a 1000-px smaller side reproducing the legacy px constant exactly, and whose px clamps protect both ends of the spectrum — a 360-px Pinephone hits the lower clamp on the larger headings, a 4K desktop hits the upper one. The tests in `theme::typography` exercise all three regimes (narrow phone, calibration point, large display) so future drift in the percentages or clamps is caught immediately. `Canvas::viewport_logical` is the only render-surface API touched. None of the existing per-frame paths (`draw_text`, `measure_text`, `font_line_metrics`) change shape, so backends and external embedders aren't disturbed. The `dpi_scale` accessor already existed; this commit only adds the convenience that ratios it against the surface size to return the unit layout actually wants. Test coverage rounds out the addition rather than just smoke-testing the happy path: 22 new tests, broken down as `types::length_tests` (7 — every variant, clamp with relative value, clamp with swapped bounds, `From<f32>`), `render::viewport_tests` (3 — scale 1, scale 2, scale 0 fallback), `theme::typography::tests` (3 — phone-clamped, calibrated, 4K-clamped), `layout::spacer::tests` (4 — px height, vmin height, vw width, flex spacer reports `None`), `layout::column::tests` (3 new — vmin spacing accumulates, vmin padding, vmin max-width caps inner-w), `layout::row::tests` (2 new — vmin padding, vmin spacing produces correct visible gap between non-flex children regardless of the row's centering anchor), and `widget::text::tests` (3 updated/new — defaults compare against `Length::px(16.0)`, `.size( f32 )` and `.size( Length )` both verified). The existing integration test in `tests/layout_stack_spacer.rs` is updated to call `Spacer::preferred_size( &canvas )` and compare `fixed_height` / `fixed_width` against `Some( Length::px( n ) )`. Documentation is updated end-to-end so the new API is discoverable from `cargo doc` without grepping the source: `lib.rs` gets a new entry for `Length` under the **Types** section and a new **Designing for multiple resolutions** section that lists the three patterns (relative `Length` for sizing, responsive typography for hierarchy, `view()`-level branching on surface dimensions only when the structure itself must change). `Canvas::viewport_logical` ships with a runnable `assert_eq!` example covering the scale-2 case. The module-level docstrings for `Spacer`, `Column` and `Row` now show both an `f32` example (legacy, still valid) and a `Length::vmin( ... ).clamp( ... )` example for the responsive variant — `cargo doc` renders both side by side so the upgrade path is obvious. Out of scope for this commit, deliberate: `WrapGrid::spacing_x` / `spacing_y` / `padding`, `widget::text_edit::TextEdit::font_size`, and `widget::image::Image::size` still take `f32`. None of them are on a critical responsive path right now, the `From<f32>` shim means migrating later is a one-line setter signature change per widget, and keeping this commit focused on the widgets the lockscreen actually uses keeps the diff reviewable. The line-gap fix in `text::preferred_size` already benefits `TextEdit` indirectly because its caret/row math reads from the same metrics helpers. |

themes/default: drop the inner shadows from the launcher.svg glyph
In both `themes/default/branding/dark/launcher.svg` and `themes/default/branding/light/launcher.svg` the launcher glyph is built from nine cells, each with its own `filterN_diiii_4479_*`. Those filters layered four successive inner-shadow passes (`effect2..effect5_innerShadow_*`) on top of the outer drop shadow `effect1_dropShadow_*`: pairs of `feColorMatrix in="SourceAlpha"` + `feOffset` + `feGaussianBlur` + `feComposite operator="arithmetic"` + `feBlend`, with offsets `(-3.6,-3.6)`, `(1.8,1.8)`, `(0.45,0.45)` and `(1.8,1.8)` and blend modes `plus-lighter`, `overlay` and `normal` to reproduce the light-above / dark-below bevel and inner halo of the original Figma export. That is twenty-four lines per cell and nine cells per file — 216 lines per SVG, 432 in total. This change removes those four inner-shadow passes in both files; the outer drop shadow (`effect1_dropShadow_*`), the `clipPath` with `bgblur`, the `rect` elements defining each cell and the rest of the document are kept verbatim. The launcher silhouette and its placement do not change: the icon still occupies the same `viewBox` and produces the same clip; what disappears is the specular highlight and dark inner contour of each cell, leaving flat rectangles on the background with their projected shadow. The diff is pure deletions, with no added lines, and the existing difference between the `dark` and `light` variants is preserved (only the filter identifiers differ, `_38862` versus `_38700`). |

add Carousel widget and WrapGrid::centre_last_row
Forge's app switcher needs two layouts the existing widget set didn't cover. The desktop grid wants a partial last row centred under the rows above (3 tiles → row 1: two, row 2: one centred) so a 7-of-9 leftover band reads balanced rather than left-aligned. The mobile variant wants a horizontal carousel where the focused tile sits centred in the viewport at a configurable fraction of its width and its neighbours peek out on the sides at a fixed gap.
Extend `WrapGrid` with `centre_last_row( bool )`. When set, layout offsets a row that has fewer than `columns` children by `(missing * (cell_w + spacing)) / 2` so it stays centred inside the content rect. Defaults to false; every existing call site continues to land tiles flush-left. Covered by three layout tests (centred partial row, full row no-op, off-by-default).
Add the `Carousel` widget at `src/widget/carousel/`. It is a pure layout primitive: `focused_width_frac` (0.05–1.0, clamped), `gap` and `offset` are owned by the caller, leaving drag / inertia / snap policy to the host so the compositor can plug in its existing touch pipeline. Each child gets a rect at `base_x + idx * (child_w + gap)` and the full viewport height; `snap_offset( viewport_w, idx )` translates index to centring offset and `focused_index( viewport_w )` rounds the current offset back to the nearest tile. Plumbed into `Element::Carousel` with the matching arms in `widget/element.rs` and walker in `draw/layout.rs`; re-exported as `ltk::{ Carousel, carousel }`. Covered by nine unit tests (layout, offset shift, snap / focus round-trip, frac clamp, child height) plus a `cargo run --example carousel` demo with Prev / Next / arrow-key navigation against an external offset state. The example is wired into the `examples` Makefile target.
Updates the widget catalogue and the `widget/mod.rs` landing comment to list the carousel under "Clipping wrappers" and to mention `centre_last_row` in the grid section.

app, event_loop: first-frame-committed hook and foreign_toplevel app_id only
Two independent changes, both blockers for a working desktop session through the loginmanager-daemon handoff and the dock's running-app icons. `App::on_first_frame_committed` is a new trait hook fired exactly once, immediately after the very first `wl_surface.commit` of a rendered buffer on the main surface. `AppData` grows a `first_frame_committed: bool`, `draw_frame` now returns whether this call performed that first commit, and `try_run` invokes the hook after the borrows held during the draw are released. Used by the loginmanager-daemon-aware crustace path to signal "ready to be presented" back to the daemon as soon as the GPU has the first frame — the actual present can still be deferred under VT switching (no DRM master yet), but the client-side commit is the right edge for handoff. `toplevel_display_id` in the foreign-toplevel-list handler no longer falls back to `info.title` or `info.identifier` when `info.app_id` is empty. Smithay creates each `ext-foreign-toplevel-list-v1` handle with `app_id = ""` and `init_new_instance` flushes a `done` immediately, so subscribers used to see the protocol-level identifier (a 32-char `Alphanumeric` random token) as the "app id" of every new toplevel — and remained stuck on it whenever the client's real `set_app_id` arrived between done events but the subscribing app's matcher couldn't resolve it to a `.desktop` entry. Returning the raw `app_id` (empty or not) makes that first transient `done` ignorable by the consumer's own empty-string guard; the second `done`, carrying the real app id, is processed normally. |

layout/stack: opt-in Stack::fit_content() so a wrapping container can adopt the stack's intrinsic size
`Stack::preferred_size` unconditionally reported `(max_width, max_h)` — every stack claimed the full width its parent offered, regardless of what its children actually needed. That is the right default for a FrameLayout-style overlay (the existing callers all rely on it) but it makes the natural "pin a stack to a fixed-size child (e.g. a spacer of `card_w × card_h`) and centre other children on top of it" pattern impossible: a container wrapping such a stack always inherited the full parent width and ignored the spacer's footprint. The new `Stack::fit_content()` builder mirrors the `Column::fit_content` flag — when set, `preferred_size` returns the max of children's intrinsic widths and heights instead of claiming the parent's `max_width`, with the same "skip filler widgets that themselves claim `max_width`" exclusion list (`Spacer` with no `fixed_width`, `Separator`, `Scroll`, `ProgressBar`, `Slider`, `TextEdit` without `fixed_width`) so the flag is not defeated by a flexible child slipping into the stack. Default behaviour is unchanged. |

doc: silence rustdoc intra-doc warnings (private-item links and palette/surface ambiguities)
`cargo doc --no-deps` was emitting eight warnings about intra-doc links resolving to private items or ambiguous fn/module names. None reflect a behaviour bug; they were just noise that cluttered the docs build output. Five of the warnings came from doc comments that cross-referenced items not in the rendered public API. `widget::scroll::Scroll` (struct), `Scroll::horizontal`, `Scroll::both`, `event_loop::text_editing` (module) and `text_shaping` (module) are all `pub` in their own modules, but the `widget` and `event_loop` parents are private to the crate root, so rustdoc treats them as private when resolving links from items that ARE on the public surface (`ScrollAxis`, the `scroll` constructor, `font_bytes`, the `text_edit` module docs). The fix is to drop the link syntax for those references: keep the identifier in backticks (so it still renders as code) but remove the surrounding `[...]` so rustdoc doesn't try to resolve it. Where the cross-reference had no semantic load beyond "see this module", the prose is rephrased to name the module without trying to link to it (e.g. "the `event_loop::text_editing` private module", "see the `text_shaping` private module"). The remaining three warnings were `palette` / `surface` linking ambiguously between a module of that name and a function of the same name within `crate::theme`. Adding `()` after the identifier inside the brackets (`palette` → `palette()`, `surface` → `surface()`) disambiguates to the function, which is the intent in all three sites — the surrounding text talks about "per-slot shorthand accessors", which is what the functions are. After this `cargo doc --no-deps` runs clean with no warnings. |

input/keyboard: fall through to App::on_key when the Enter dispatch target widget has no submit/press message
`handle_key_return` previously routed `Return` to either the focused or hovered widget's submit/press message and, only when neither index existed, fell through to `app.on_key_with_modifiers`. If a stale `hovered_idx` (left over from a prior screen) pointed at a widget that exists in the new `widget_rects` but exposes no submit or press handler, `target.is_some()` was true and the message-less dispatch silently swallowed the key — the `else` branch never ran and `App::on_key` never saw the keysym. This manifested in the eydos-loginmanager greeter as `Enter` on the Lock screen failing to fire `Message::Unlock` after a pause/resume cycle, until the user clicked something to refresh `hovered_idx`. Track whether the widget path actually pushed a message and, when it didn't, fall through to the app-level handler so the `Return` keysym still gets a chance to be interpreted by the application's `on_key`. No behaviour change when the focused/hovered widget does provide a `submit_msg` or `press_msg`. |

fix(event_loop): walk error source chain for BrokenPipe in OtherError
The previous fix checked downcast_ref::<io::Error> directly on the OtherError payload, but wayland-client wraps the io::Error inside WaylandError::Io — one level deeper. Downcast failed, is_closed stayed false, and the panic arm fired anyway. Replace the single downcast with a source()-chain walk that finds the io::Error at any depth, matching the same BrokenPipe / ConnectionReset check already used for the direct IoError arm. |

fix(event_loop): exit cleanly on OtherError(BrokenPipe) from compositor
calloop surfaces the closed-socket condition either as Error::IoError(BrokenPipe) — already handled — or as Error::OtherError wrapping an std::io::Error with kind BrokenPipe, which previously fell through to panic!(). Add a matching arm that downcasts the inner error and treats both forms the same: log and set exit_requested so the run loop terminates gracefully instead of unwinding. |

event_loop, a11y, text_shaping: AccessKit AT-SPI2 bridge, cross-app clipboard, xdg-activation, HarfBuzz shaping, multi-touch hooks
Five orthogonal capabilities land together because they share the same `try_run` plumbing: an optional global is bound at startup, a piece of state is added to `AppData`, the run-loop iteration drains an inbox / pushes a frame snapshot, and the public surface gains a small set of opt-in `App` hooks. Nothing here breaks an existing app — every new path degrades to a no-op when the compositor does not advertise the relevant global or when the platform adapter cannot start. AT-SPI2 accessibility via AccessKit. A new `src/a11y/` module owns the platform adapter and the inbound `ActionRequest` channel. `A11yState::try_new` constructs an `accesskit_unix::Adapter`; when the AT-SPI2 daemon is not on the session bus (headless CI, locked-down compositors) the constructor returns `None` and the rest of the pipeline runs unchanged. After every successful `draw_frame`, the run loop builds a fresh `accesskit::TreeUpdate` from `widget_rects` and pushes it through the adapter — main surface plus every visible overlay, each translated to global coordinates via `surface_offset_for` so screen readers report positions in the same frame the user sees. Buttons / toggles / checkboxes / radios / list items / sliders / text edits map to the matching `Role`s; `Click` and `Focus` actions are advertised on every interactive node; inbound action requests are drained at the top of each iteration and translated into a synthetic press / focus on the matching widget. The integration is documented as best-effort in `docs/architecture.md` under "Known gaps and non-goals": hierarchical nesting, per-widget accessible names, live regions and `Action::SetValue` are listed as the natural follow-ups that the foundation now supports but does not yet wire. Cross-application clipboard via `wl_data_device_manager`. A new `src/event_loop/data_device.rs` bridges the existing process-local `clipboard: String` to the Wayland selection. Outbound (Ctrl+C / Cut): after the local clipboard is populated, `publish_clipboard_selection` creates a `CopyPasteSource` offering `text/plain;charset=utf-8` and installs it as the seat's selection; `DataSourceHandler::send` writes the cached string into the fd the peer hands us. Inbound (Ctrl+V from another app): `DataDeviceHandler::selection` asks for the offered text via `WlDataOffer::receive`, spawns a tiny worker thread to drain the read pipe with a 16 MiB cap to prevent paste-bomb DoS, and posts the result back through an `mpsc::Sender` that the run loop drains each iteration into `data.clipboard`. The `clipboard:` field's doc-comment is updated to reflect the new behaviour: process-local when the compositor does not advertise the global, synchronised with the seat selection otherwise. External drag-and-drop reception. The same `data_device` module handles `DragOffer` enter / motion / leave / drop_performed: `on_drop_motion( x, y )` fires while the drag hovers over the surface, `on_drop_leave()` when it withdraws without dropping, and `on_drop_received( x, y, mime, text )` when an external payload (`text/uri-list`, `text/plain`, …) is released on top of an ltk window. The receive path reuses the same worker-thread / channel pattern as the clipboard so the run loop never blocks on the read fd. Three new `App` hooks expose the events with no-op defaults; apps that ignore them get the previous behaviour. `xdg-activation-v1`. The global is bound optionally; when it is present, `try_run` reads `$XDG_ACTIVATION_TOKEN` from the environment, removes it immediately (single-use; preventing leaks into child processes) and stashes it on `AppData::activation_token_pending`. After the first successful configure of the main surface — the earliest point at which `xdg_activation_v1.activate` is meaningful — the token is consumed once and the surface raised to focus. Compositors without the global leave `activation_state` as `None` and the inbound path silently degrades. An `App::request_activation_token` outbound path is reserved on the trait but not yet exercised here. HarfBuzz shaping. A new `src/text_shaping.rs::shape_line` drives both renderers: the logical-order string is run through `unicode-bidi`, split into per-font sub-runs, and shaped through `rustybuzz`. Each `PositionedGlyph` carries the per-font `glyph_id`, the visual advance and the ink offsets — exactly what `fontdue::Font::rasterize_indexed` needs to render Arabic connected forms, Devanagari clusters and CJK shaped glyphs correctly. The GLES atlas is re-keyed on `(glyph_id, size_bits, font_id)` so glyphs from different fonts at the same size no longer collide, and the atlas format is selected per ES profile (`GL_R8` / `GL_RED` on ES3, `GL_LUMINANCE` on ES2) — the fragment shader samples `.r` for both, since `GL_LUMINANCE` replicates the coverage byte into `.r=.g=.b`. Software path follows the same key. New `Cargo.toml` deps: `unicode-bidi = "0.3"`, `rustybuzz = "0.14"`. Multi-touch hooks. `App::on_touch_down / on_touch_move / on_touch_up( id, x, y )` expose the raw `wl_touch.id` of every secondary finger. The first finger to land remains the *primary slot* and is fed through the regular gesture machine (`on_pointer_*`, swipe, scroll, long-press, drag-and-drop). Every additional finger fires the new callbacks instead, leaving the existing single-slot behaviour untouched for apps that do not override them. This is the substrate for app-defined pinch-zoom / two-finger pan; the toolkit itself does not yet ship a built-in pinch gesture (called out in the same "Known gaps" doc section). `event_loop::frame` extracted from `draw/mod.rs`. The `draw_frame` orchestrator and its per-format SHM helper (`pick_shm_format`) move into `src/event_loop/frame.rs`, leaving `draw/` strictly responsible for per-surface paint primitives. The import in `event_loop/run.rs` is rewritten accordingly; `draw/mod.rs` shrinks from 192-line orchestrator to a thin module index. Overlay teardown safety. `AppData::discard_overlay( id )` synchronously removes a destroyed overlay from the map and rewrites every per-device focus that pointed at it (pointer, keyboard, every touch slot), migrating an in-flight long-press drag to the main surface the same way `reconcile_overlays` does. Used by the compositor-driven destruction paths (`PopupHandler::done`, `LayerShellHandler::closed`) where waiting for the next reconcile would leave a window in which `surface()` / `surface_mut()` panic. The non-panicking siblings `try_surface` / `try_surface_mut` are added for callers on async dispatch paths (IME `Done`, tooltip arm) that may race a teardown. Miscellaneous. CI: `master` → `main` to match the actual default branch. `Makefile` adds `cargo run --example dialog` to the examples target. `src/lib.rs` re-exports `widget::scroll::ScrollAxis` so apps can configure a `scroll()` axis without reaching into a `pub(crate)` module. `Cargo.toml` adds `accesskit = "0.17"` and `accesskit_unix = "0.13"`. `docs/architecture.md` gains the "Known gaps and non-goals" section that enumerates the new capabilities, what still ships flat, and what is deferred (per-widget a11y labels, primary selection, intra-process multi-touch gestures, `wp_fractional_scale_v1`). |

refactor: split every monolithic module into focused submodules
Each source file that had grown beyond a single concern is replaced by an identically-named directory containing focused submodules. `src/event_loop/mod.rs` (878 lines) becomes a directory with clipboard, context_menu, cursor_shape, drag, focus, handlers, invalidation, overlays_reconcile, repeat, run, surface, text_editing, and tooltip. Every widget, input handler, and theme component follows the same split. Public interfaces are unchanged — only the internal file layout moves. image bumped from 0.25.2 to 0.25.9. |

input/keyboard: let the app intercept arrow / Tab keys before the default text-edit and focus-shift behaviours
The keysym dispatcher used to give the focused widget first refusal on Left / Right / Up / Down / Tab. A `text_edit` swallowed the four arrows for cursor movement, and Tab walked the keyboard-focus ring through `next_focusable_index`. Apps only got `on_key_with_modifiers` for those keys when no text input was focused (Tab never), so a search field with autocomplete couldn't drive a selection cursor through arrows or Tab without putting focus on something else first — which is exactly the wrong UX for a search-as-you-type list. Three arms in `AppData::handle_key_press` now query `self.app.on_key_with_modifiers( keysym, ctrl, shift )` *first* and only fall back to the default behaviour if the app returns `None`: - `Left | Right`: previously branched on `is_text_input` and routed the keypress to `handle_cursor_left/right` for text fields, otherwise asked the app. Now: app first; if app says `None`, the existing text-cursor path runs for text inputs and non-text widgets get nothing (their previous fallback already produced no useful action without an app handler). - `Up | Down`: the previous logic was a four-way decision that tried text-cursor movement, then `move_keyboard_hover` for combo / list widgets, then the app handler. Now the app gets first refusal too. When it declines, the original cascade (text-cursor → hover navigation) still runs, so multiline `text_edit` cursor walking and combo / scrollable-list keyboard nav are unchanged for any app that doesn't intercept these keys. - `Tab | ISO_Left_Tab`: app first; on `None` the focus-shift path (`next_focusable_index` + `set_focus`) runs. Apps that want Tab as a navigation message between custom UI states (a search field cycling through results, a wizard advancing pages) finally have a hook; apps that don't get the standard tab-through-focusable behaviour by leaving `on_key_with_modifiers` returning `None` for Tab, which is the trait's default. The interception is keysym-only — modifier state is forwarded so an app can distinguish `Tab` from `Shift+Tab`, `Right` from `Ctrl+Right`. The text-input check is preserved as a local before the dispatch so the fallback doesn't lose the "is this even a text edit?" question; it just runs *after* the app instead of before. Net effect: a list / autocomplete that needs arrow / Tab navigation can now be implemented purely by overriding `App::on_key_with_modifiers`, with no changes to `text_edit` itself and no risk of breaking apps that don't need it. The Up / Down branch's old comment about the "fall through to list hover-navigation" rationale is dropped — the cascade still exists, but the app-first ordering is the new contract and the comment was about the previous one. |

event_loop, widget, input: pointer-dwell tooltips, global drag coords, foreign-toplevel name cascade
`Button::tooltip( text )` registers a hint string that fires after a 600 ms pointer dwell. `LaidOutWidget` gains a `tooltip: Option<String>` field, `Element::tooltip()` exposes it to the input layer, and the existing pointer-hover path now calls `arm_tooltip` on hover-enter and `cancel_tooltip` on hover-leave / touch. The deadline is polled alongside `next_long_press_wakeup` in `try_run` so an idle pointer still gets a wake-up at the firing instant; on fire, `tooltip_overlay()` synthesises an `OverlaySpec` — a rounded `text_primary @ 95%` pill drawn with `bg` text — anchored above the hovered widget, flipping below or clamping inside the screen if it would clip, and pushed alongside the app's own overlays both in the redraw path and in `reconcile_overlays` so the layer surface is created the same frame the tooltip becomes visible. Pointer-only by design: touch events explicitly cancel because a tap-and-release should never linger into a hint. The `showcase` example wires `.tooltip(..)` on the three button variants as a smoke test. The drag pipeline now reports positions in main-surface (global) coordinates instead of per-surface. `surface_offset_for( focus )` derives the top-left of an overlay surface from `SurfaceState::layer_anchor` — newly stored at `reconcile_overlays` time from `OverlaySpec::anchor` — combined with the main surface's dimensions; `on_drag_move`, `on_drop`, the synthetic move emitted on drag-promotion in `pointer.rs`, and the `pending_drag_inits` push site in `gesture::start_drag` all translate before handing coordinates to the app. The motion and release paths additionally `request_redraw()` every overlay so a dock-style drop target painted on an `Anchor::Bottom` layer surface gets repainted as the drag moves — without that, the visible drop indicator only updates when the cursor re-enters the main surface. Drops still target whichever surface fired the release; only the coordinates are unified. `ForeignToplevelListHandler` previously read `app_id` directly via `ForeignToplevelList::info()`. Clients that never set `app_id` (some winit-windowed compositors, simple test clients) were silently invisible to crustace-style docks because the empty string fell through `unwrap_or_default()` and the dock then keyed entries off `""`. `toplevel_display_id()` cascades: prefer `app_id` for desktop-entry matching, fall back to `title` for human-readable identification, and finally to the protocol-issued `identifier` which is always present and unique per handle. Applied to both `new_toplevel` and `update_toplevel`. `theme::system_fontdb()` lazily loads the system font database once via `OnceLock` and reuses the `Arc` for every `decode_svg_bytes` call. resvg's default `Options::fontdb` is empty, so any SVG containing `<text>` rendered with the built-in fallback font or no font at all; with the system DB attached, icons and decorative SVGs with embedded labels now resolve glyphs correctly. Cached because `load_system_fonts()` walks every font path on the system and is comfortably tens of milliseconds on a cold cache — not something to repeat per icon decode. `themes/default/theme.json` tweaks one variant's slot palette: `surface-alt` from `@indigo/D9` to `@white/D9` and `text-primary` from `@white` to `@navy`, plus a cosmetic re-alignment of the `"value"` columns in the same slots block. |

container, text, date_picker: width-aware sizing pass
`Container::max_width(px)` mirrors the same flag on `Column` / `Row` — the container reports `min( offered, px )` upwards and the draw pass caps `rect.width` to `px`, so a decorated child wrapped in `container().max_width(260)` no longer needs a `column()`-of-one shell just to access the cap. Propagated through `map_msg`, covered by a test, and documented under the `container` section of `docs/widgets.md`.
`Text::no_truncate()` opts out of the default ellipsis behaviour: when `truncate = false` the draw pass paints the full string even if `measure(text) > rect.width`. Useful for very short labels (calendar days "1"–"31", day-of-week stubs "Lu" / "Mi" / "Sá") inside grid slots whose width is dictated by the parent — a couple of pixels of overflow centred in the rect is invisible, while "..." in place of a single-digit number is loud.
`DatePicker::width(px)` is a layout hint: when set, `build()` derives `header_fs`, `dow_fs` and `day_fs` from the slot width so the worst-case label in each row ("September 2026" in the header, "Mié" / "Sáb" in the DOW row, "30" in the day cell) fits at a sensible size; the design defaults stay as upper bounds. Day and DOW cells also flip on `Text::no_truncate()` as a safety net — heuristic font sizing can't perfectly predict glyph widths across families, and overflowing one pixel beats truncating to "...".

event_loop: route take_focus_request to widgets on overlay surfaces
The `take_focus_request` block in `try_run` only searched `data.main.widget_rects` for the requested `WidgetId`, so an app that wanted to focus a widget living on an overlay surface (a search field on a launcher overlay, a text edit on a dialog modal, a password field on a popup) silently no-op'd: the widget existed and had been laid out, but the lookup never found it because it was scanning the wrong `widget_rects`. Crustace hit this trying to put cursor focus on the launcher search field when the launcher slides up — the field rendered with a visible caret but typing went to whoever the keyboard had been focused on before. The lookup now falls through to `data.overlays.iter()` if the main scan misses, returning the first `(SurfaceFocus::Overlay(id), flat_idx)` whose surface carries a widget with that id. `data.set_focus` already accepts the `SurfaceFocus` discriminant, so the call site just forwards what the lookup found and requests a redraw on the matching surface instead of unconditionally on main. No effect on apps that target main-surface widgets — the main scan still runs first and short-circuits the overlay walk. |

theme, event_loop: window_controls.bar_bg slot + graceful exit on compositor disconnect
`WindowControlsSpec` gains `bar_bg`, the background fill of the SSD title-bar strip the close / maximize / minimize controls sit on. Forge used to paint that strip with `palette.surface` clamped to alpha 1.0 — a hack on a translucent panel token. With a dedicated slot the theme decides directly: `@off-white` in light and a new `@window-bar-dark` shade in dark. Schema gets the matching `Option<String>` field (defaulting to `palette.surface` to keep existing themes rendering the same) and the fallback `WindowControlsSpec` seeds `Color::WHITE` so a missing theme still draws something readable.
`try_run`'s dispatch loop previously `.expect("dispatch")`-ed every calloop error. When the compositor closes the wayland socket — `wl_display.error`, forge crashing, the user logging out — the loop saw a `BrokenPipe` / `ConnectionReset` and panicked, which polluted the user's stderr with a backtrace for what is just "the session ended". The match now treats those two `IoError` kinds as a clean shutdown: it prints `Connection::protocol_error()` (the typed `wl_display.error` if the server sent one), sets `exit_requested = true`, and lets the loop drain out normally. Any other dispatch error keeps panicking — those are still genuine bugs.

event_loop: client binding for ext-foreign-toplevel-list-v1
Adds an `App` callback that delivers the live list of open toplevels from the compositor — the data source a shell needs for dock running-app indicators, taskbar tiles, alt-tab and any other "what is currently running" UI. Hand-wiring the protocol binding from every shell that wants it is the kind of boilerplate ltk should absorb once: this is that move.
`Cargo.toml` adds `"staging"` to `wayland-protocols`' feature list. SCTK 0.20 already pulls staging in transitively (it carries `foreign_toplevel_list.rs` and its own dispatch helper), so this is belt-and-braces against a future ltk tree that swaps SCTK for a different client toolkit — it keeps the protocol available crate-wide even then. `src/app.rs` introduces `ToplevelEvent { Opened { id: u32, app_id: String }, Closed { id: u32 } }` and `App::on_toplevel_event( &self, ToplevelEvent ) -> Option<Self::Message>` with the default returning `None` so apps that do not care pay nothing (no allocation, no dispatch). `id` is the Wayland protocol id of the handle proxy — unique per session, stable for the handle's lifetime, the same value paired across `Opened` and `Closed`. `src/lib.rs` re-exports `ToplevelEvent` from the public prelude.
`src/event_loop/app_data.rs` grows a `pub foreign_toplevel_list: ForeignToplevelList` field. `src/event_loop/mod.rs` constructs it via `ForeignToplevelList::new( &globals, &qh )` and stores it on `AppData`. If the compositor does not advertise the global the inner `GlobalProxy` just resolves to "absent" and the list yields no toplevels — no error path needed at construction. `src/event_loop/handlers.rs` adds the `Proxy` import, `delegate_foreign_toplevel_list!( @<A: App> AppData<A> )` next to the rest, and implements `ForeignToplevelListHandler` for `AppData<A>`. The three SCTK callbacks (`new_toplevel`, `update_toplevel`, `toplevel_closed`) each pull the handle's protocol id and its currently-cached `app_id` from the list's info cache, call `self.app.on_toplevel_event( … )`, and push the returned message onto `pending_msgs` so it flows through the normal `update` cycle with the regular `invalidate_after` scoping path. `update_toplevel` re-emits `Opened` with the latest info — compositors fire this on title changes too, not just `app_id` changes, but apps whose state is keyed on `(id, app_id)` can absorb the repeat idempotently and apps that need title-change granularity can scope via `invalidate_after`.
The wire-up is generic: a shell that wants finer behaviour (focus follow, per-title indicators, multi-window grouping) can layer on top by translating the event into more specific app messages. The default app pays zero, the shell that opts in gets a real event stream without touching `smithay-client-toolkit` directly.

container: generalise background from Color to Paint
`Container::background` now stores `Option<Paint>` instead of `Option<Color>`, and the builder accepts `impl Into<Paint>` so callers can pass a plain `Color` (auto-wrapped in `Paint::Solid` via the trait impl) or an explicit `LinearGradient` / `RadialGradient`. `layout_and_draw` switches from `canvas.fill_rect( rect, bg, corners )` to `canvas.fill_paint_rect( rect, &bg, corners )` to consume the wider type. No behaviour change for existing call sites — solid-colour containers keep working unchanged thanks to the `Into<Paint>` for `Color`. |

event_loop: honour App::window_size_hint() on the first configure
Previously only `set_min_size()` was called with the requested size, on the assumption that the compositor would adopt it as the initial dimension. In practice that doesn't hold: xdg-shell has no "preferred initial size" primitive and compositors are free to pick any size within `[min, max]` on the first configure. The window ended up opening at the 800x600 fallback instead of the size the application had asked for. The fix pins `min == max` before the first commit, which forces the compositor to honour the requested size in its first configure, and then releases `max_size` from the configure handler via the `pending_size_hint_unpin` latch so the surface remains user-resizable afterwards. The 800x600 fallback now only applies when the application does not provide a hint. |
