## Overview

Agenda UnB is a campus event discovery platform paired with a private academic organizer. The visible flow is entry through the routed React app, event browsing and filtering, then opening an event detail; account creation and sign-in are handled through shared auth state backed by Supabase. The README also describes syllabus upload and automatic date extraction, but the backend source is empty and that processing flow is not evidenced in sampled code. Database migrations establish additional event and agenda storage; runtime wiring beyond the sampled profile operations is uncertain.

Main entry points: [`src/contexts/AuthContext.jsx`](https://github.com/unb-mds/2026-2-agendaunb/blob/main/src/contexts/AuthContext.jsx) (Auth provider), [`src/pages/SecondPage.jsx`](https://github.com/unb-mds/2026-2-agendaunb/blob/main/src/pages/SecondPage.jsx) (Event browsing), [`src/main.jsx`](https://github.com/unb-mds/2026-2-agendaunb/blob/main/src/main.jsx) (Route entry), [`src/App.jsx`](https://github.com/unb-mds/2026-2-agendaunb/blob/main/src/App.jsx) (Landing and account UI)
