   - `ICON_COLOR_TOOLBAR` (16/32); default `#5AC3D6`.
 - Firefox does not require .ico; PNG is recommended.
 - Theme variants can be added later via `browser_action.theme_icons`.
- - Rasterizer: the script will use `rsvg-convert` if available, then `inkscape`, and falls back to ImageMagick (`magick`/`convert`). Install one of these locally.
+- Rasterizer: uses ImageMagick only (`magick` or `convert`). Ensure your ImageMagick build supports reading SVG (via `librsvg` or compatible delegate).
