Judo NW

• Weight categories, belt grades, age divisions
• Stripe checkout, webhooks, per-size stock
• Admin area so the club runs it themselves

A judo club needed to stop taking entries by email. This models the actual sport — weight categories, a different belt system per tournament, age groups and divisions — then handles payment, entry forms, confirmation emails and a merchandise shop with stock by size. The club administers all of it without me.
