Each site now sets its own TTL (10s default, 300s cap), and serves the last good page while the app errors or the entry refreshes, with one upstream request per missing entry. The cache key carries the host, so purge clears only this site's files instead of every site's cache. The settings panel shows the 24h hit ratio.
