## Description: Adds `stale-if-error=86400` to the `Cache-Control` header set on the rendered app shell (`/`) in [src/server/RenderHtml.ts](src/server/RenderHtml.ts). This lets shared caches (CloudFlare, nginx `proxy_cache`) keep serving the last good `index.html` for up to 24h if origin returns a 5xx, alongside the existing `stale-while-revalidate` window. Pairs with enabling HTML caching for the `/` route on CloudFlare in "respect origin headers" mode — it already honors `s-maxage` (5 min edge TTL) and `stale-while-revalidate`; this just extends the same safety net to origin-error cases. No behavior change for successful responses; browsers still revalidate every load via `max-age=0`. ## Please complete the following: - [x] I have added screenshots for all UI updates - [x] I process any text displayed to the user through translateText() and I've added it to the en.json file - [x] I have added relevant tests to the test directory - [x] I confirm I have thoroughly tested these changes and take full responsibility for any bugs introduced ## Please put your Discord username so you can be contacted if a bug or regression is found: jish --------- Co-authored-by: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
