Footer now compares the running SOURCE_COMMIT against origin/main via Gitea's compare API and renders "build <sha> (latest)" when up to date or "build <sha> (N behind)" otherwise — so it's obvious from any page whether the deploy is current. Per-SHA cache (60s TTL, 1.5s timeout) keeps the lookup off the hot path in steady state. Network or parse errors return None and the parens suffix is just hidden — the SHA itself always renders, so a flaky git host can never break the layout.
