Saracens club manager

An experiment for Brayner: a management system for a junior rugby club. Membership across age groups U6–U18 (one per school year), each with its player squads, coach and team manager — and a shared club diary of training, matches and events. The backend is mocked for now — the UI talks to a fake async API backed by localStorage, so it comes loaded with demo data you can edit or wipe, and a real server can be swapped in later without touching the UI.
