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.
- 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.
- Theme variants can be added later via `browser_action.theme_icons`.
