The extension linked nothing and the resolver saw no requests: the content script
fetched http://localhost:8787 directly from the HTTPS reddit page, which reddit's CSP /
mixed-content blocks. Move the network call to a background script (extension origin,
exempt) and add stage logging so failures are visible.
- extension/background.js (new): does the resolver fetch on message; sets the toolbar badge.
- extension/content.js: talks to background via runtime messaging (no page-context fetch);
[rsl] console logs at boot/root/candidates/resolve/scan; single primary link.
- extension/manifest.json: background.scripts + browser_action (icon.svg, title).
- extension/{styles.css,icon.svg}: platform-coloured link (green=spotify, teal=bandcamp) + toolbar icon.
- service/lib.js: primaryOf()/isSearchUrl() — link Spotify when the artist is on Spotify,
else Bandcamp, else Spotify search; spotifyResult/mbResult attach `primary` (unit-tested).
- README: link behaviour, toolbar, Troubleshooting.
Verified: scripts/check.sh green (10 tests); resolver returns `primary` end-to-end. The
in-browser fix is logic-verified only (no headless Firefox here) — reload the temp add-on
and watch the page console `[rsl]` logs to confirm.

Firefox MV2 content script that detects artist/band names in reddit comment
threads and rewrites them inline into Spotify + Bandcamp links, backed by a tiny
zero-dependency Node resolver that confirms each candidate against the Spotify Web
API (direct links) or MusicBrainz (zero-setup, search links). Includes build +
install instructions in the README.
