+The visible LinkLog brand text uses the Google Foundry `Asset` font. Docker image builds download and bundle Asset, DM Sans, and Space Grotesk under `/static/fonts`, so the web frontend loads fonts from the LinkLog server rather than Google. The Firefox extension uses its bundled assets and local fallback fonts without requesting Google Fonts.

 ### Assistant outcome
 Found the actual regression in the direct-refresh update: `Promise.all([loadUsers(), loadTags()]).then(loadFeed)` passed its results array into the new `selectedTag` parameter. The feed then attempted to call `toLowerCase()` on that array during initialization. Restored the v0.1.0 callback shape with `.then(() => loadFeed())`, retained direct selected-tag refreshes, added a regression assertion, and cache-busted the feed asset to `feed.js?v=12`.

+### Assistant outcome
+Removed the web frontend's Google Fonts import and added a Docker build-time font bundling script. Image builds now download pinned Asset, DM Sans, and Space Grotesk files into `frontend/static/fonts`, generate a local `fonts.css`, and serve them through LinkLog at `/static/fonts`. The Firefox extension did not make Google Font requests and continues to use bundled assets with local fallback fonts. A clean image build confirmed all nine local font assets are present.
