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

Place the final PNGs for the add-on icon here. 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
-----
- Use the same artwork at each size; keep transparent backgrounds.
- Source: a 128×128 PNG is perfect; export downscaled versions for 96/48/32/16.
- 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.

Quick export (ImageMagick)
