Icon assets
===========

PNG icons are generated from `file-search.svg` during the build.
Run `npm run build` (or `npm run build:icons`) to regenerate. The manifest is wired to use:

- Toolbar (browser_action → default_icon):
  - icons/icon-16.png
  - icons/icon-32.png
- Extension/Store (top-level icons):
  - icons/icon-48.png
  - icons/icon-96.png
  - icons/icon-128.png

Notes
-----
- Source: `icons/file-search.svg` uses `stroke="currentColor"`.
- The build script replaces `currentColor` with configured colors and rasterizes with a transparent background. It also injects explicit `stroke`/`fill` on each path for better compatibility across renderers.
- Default stroke colors use the project emphasis palette:
  - Add‑on icons (48/96/128): Primary 2 (deep) `#223544`.
  - Toolbar icons (16/32): Primary 1 (light) `#5AC3D6`.
- Customize via env vars when building:
  - `ICON_COLOR_ADDON` (48/96/128); default `#223544`.
  - `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.
