Key points

• Migrations are applied automatically on start.
• Schedule the purge: GET /api/v1/cron/purge with Authorization: Bearer $CRON_SECRET (hourly recommended).
• The bucket must allow PUT and GET from your domain (CORS).
• Always serve the app over HTTPS: browser-side encryption depends on it.
