Sends to every registered device matching the filter, across all users. First segment send may ask Firestore to create an index - follow the link in the error, wait a few minutes, retry.

Checked every 5 minutes - actual delivery lands within ~5 min of this time.

Goes to ALL users with a registered device - one queue entry per user, firing at this wall-clock time in their own timezone (e.g. 9:00 AM in Austin, 9:00 AM in Sydney). Honours each user's Marketing toggle. Users whose local time already passed on this date are skipped - pick tomorrow for full coverage. Delivery lands within ~5 min (cron).
