Initial Camp Scan ticketing system

Backend (Fastify + TS): FluentForms webhook -> NocoDB row + QR + MailerSend
email; PIN auth; scan/lookup/redeem with per-code serialization; reusable QR
codes with count-based check-in; admin search.

App (Expo, one codebase): Android APK + iPhone PWA. Login, camera scanner
(native + web barcode-detector split), green/red overlay with sound + haptics,
admin lookup/redeem. Session token persisted per device.

Ops: multi-stage Dockerfile serving API + PWA same-origin, compose bound to
