perf(frontend): cache hashed assets and fonts long, revalidate index.html on Firebase - #609

Conversation
…html on Firebase Vite emits hashed files to /assets (the old rule matched the CRA-era static/ path), so fonts had no long cache header. index.html now revalidates, so a new deploy is picked up immediately and never references already purged chunks from a stale copy.

What
Cache headers in
frontend/firebase.jsonfor the Vite build output:assets/**and*.woff2getmax-age=31536000, immutable. The old rule targeted the CRA-erastatic/**path, which does not exist anymore, so the fonts had no long cache header./and/index.htmlgetno-cache(revalidate with ETag, a cheap 304). Without it Firebase's default one hour cache can serve an oldindex.htmlthat references hashed chunks of a previous deploy.Firebase Hosting already compresses text responses (gzip/Brotli), so no compression change is needed. Permalinks use the URL hash, so the app is only entered via
/or/index.html.Verification
Only the JSON syntax is checked locally, the headers cannot be exercised without a Firebase deploy. After deploying, check:
Dependencies
None.
Deployment notes
None beyond the usual Firebase deploy.
