Error message

no announcement available (404 on /announcements/latest)

What it means

A 404 on GET /announcements/latest is semantically "no announcement right now", so authed_json maps it to the typed AnnouncementNotFound; the announcements caller degrades to null instead of propagating an error. Best-effort cosmetic path, never reported to Sentry.
