 Notes
 -----
-- Use the same artwork at each size; keep transparent backgrounds.
+- Source: `icons/file-search.svg` uses `stroke="currentColor"`.
-- Source: a 128×128 PNG is perfect; export downscaled versions for 96/48/32/16.
+- The build script replaces `currentColor` with configured colors and rasterizes with a transparent background.
+- Customize colors via env vars:
+  - `ICON_COLOR_ADDON` (48/96/128); default `#111827`.
+  - `ICON_COLOR_TOOLBAR` (16/32); default `#111827`.
 - Firefox does not require .ico; PNG is recommended.
-- If you later want theme-specific toolbar icons, you can add `browser_action.theme_icons` with light/dark variants.
+- Theme variants can be added later via `browser_action.theme_icons`.

-Quick export (ImageMagick)
--------------------------
-```bash
-magick file-search.svg -resize 128x128 icon-128.png
-magick file-search.svg -resize 96x96   icon-96.png
-magick file-search.svg -resize 48x48   icon-48.png
-magick file-search.svg -resize 32x32   icon-32.png
-magick file-search.svg -resize 16x16   icon-16.png
