// AC moved off Firebase Cloud Messaging to standard Web Push (VAPID) and
// direct APNs — see shared/push.mjs. This endpoint stays only so cached
// pre-migration clients get a clean "disabled" answer instead of a 500:
// old boot.mjs treats a non-ok response as "notifications unavailable" and
// the old firebase-messaging service worker treats a null config as a no-op.
