-- push_subscriptions: Web Push endpoints for browsers / PWAs. id is the hex
-- SHA-256 of the endpoint, so a re-subscribe from the same browser upserts in
-- place rather than piling up duplicate rows. Lookups are by (user_id,
-- device_name): the receiving device of a notify-worthy event. Dead endpoints
-- (push service returns 404/410) are pruned by DeletePushSubscription.
-- NOTE: keep this file pure ASCII; sqlc v1.31.1 drifts byte offsets on
-- multibyte runes in query files, corrupting the generated SQL.
