Deployment checklist

1. Keep AUTH_SECRET configured. 2. Keep GOOGLE_CLIENT_ID configured with the OAuth client created in Google Cloud. 3. Manage authorized Google/Gmail emails from the Admin Panel; ALLOWED_EMAILS may still be used as the initial fallback list. 4. Deploy the folder with Cloudflare Pages Advanced Mode using _worker.js.
