The email field is validated to reduce delivery problems. If the operator marks the booth as closed, this page shows a closed banner and message instead.
+- **Closed page** (`/request`) — when the booth is marked closed from `/admin/settings`, visitors see the closed banner and a friendly "goblin engineers are on a break" message.
 - **Confirmation page** (`/thanks/<id>`) — shows the request number after submission.
 - **FAQ page** (`/faq`) — answers common customer questions.
 - **Private player page** (`/play/<token>`) — customer receives an email with a unique link. They can stream Version A and Version B, pick one (or both), or request a limited number of revisions.

 ## Important notes
 
 - **No `.env` file in production.** `docker-compose.yml` passes variables directly from Portainer. This avoids Portainer's `env_file not found` error.
-- **Runtime settings persist.** SMTP config, revision limit, auto-refresh interval, and MP3 metadata defaults are stored encrypted (where sensitive) in `booth_settings.json` inside the persistent uploads volume. They survive redeploys.
+- **Runtime settings persist.** SMTP config, revision limit, auto-refresh interval, booth open/closed state, and MP3 metadata defaults are stored in `booth_settings.json` inside the persistent uploads volume. They survive redeploys.
+- **Booth open/closed switch.** Operators can flip the booth status from `/admin/settings`. When closed, `/request` shows a closed banner and message instead of the form.
 - **Payments are manual.** The app records a Square payment reference but does not integrate with Square's API. Use a Square Terminal/Reader at the booth.
 - **Operator queue is the dashboard.** No operator email alerts are sent; approvals and revision notes appear as status changes in `/admin`.
 - **MP3 metadata.** Uploaded files are tagged with title (from the saved prompt), plus configured artist/album/year/comment values.
