Referees by QR code

A referee needs no account: hand them a link or a QR code and they run their bouts straight from a phone.

• each referee sees and edits only the bouts assigned to them;
• access roles to fit the job: chief referee, secretary, piste referee;
• the organiser runs the competition with full access;
• a referee's key can be reissued — the old link stops working.

This way several referees work in parallel without getting in each other's way or touching someone else's protocol.
