Start from the league referee base
Assignments only work when referees, statuses, and league links are organized before the round.
In Manage referees, the league keeps registration, contact, active or inactive status, certification, and operational link in one record. That record feeds availability, saved crews, match assignments, and the referee public view.
The screen also keeps loading, empty, permission-blocked, and plan-blocked states clear, so the organizer understands the next step without losing context.
