Email Camp — Camp Mail Tracking & Delivery System

A web app for camps to manage physical mail/letters: room and resident management, adding incoming letters with photos/notes, tracking delivery status (pending/delivered), and filtering by recipient and room. When a letter is added, the system sends an email notification to the recipient and stores the notification status (sent/not sent). Includes user roles (admin/staff/guest) plus a demo mode and a showcase section that explains features and architecture.
Tech stack: Next.js 14 (App Router), Supabase (Postgres/RLS/Storage), React Query, TailwindCSS, Resend (email delivery).
