A QR code on your own page
Anyone who leaves a recording gets a small QR code on their own profile page in the book. Scanning is enough — the recording plays in the browser, with no app and no account.
- The QR code belongs to the person, not to the recording: re-record as often as you like, the printed code keeps working.
- Record nothing and you get no gap — whatever stood there before stands there still.
