The original exports used foreignObject (CSS backdrop-filter) and
feComposite in2="hardAlpha" filter chains — Figma-specific constructs
that resvg ignores, making all nine dots invisible at runtime.
Replace both dark and light variants with plain 3×3 grids of rx=3
rounded rects (white in dark mode, #0A032E in light mode). No filters,
no defs, fully renderable by resvg/tiny-skia.
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`).
