 - **Request form** (`/request`) — visitors enter name, email, hobbies, notable facts, preferred style/genre, vocal gender preference, and extra requests. A branded banner image is shown. The email field is validated to reduce delivery problems.
 - **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.
 - **Revision workflow** — when a customer asks for changes, the current MP3s are archived and the operator sees the request as "Revisions Requested" in the dashboard.
 - **Rate limiting** — the public request form is capped at 5 submissions per minute per IP.
