## Key Files

| File                             | Purpose                                   |
| -------------------------------- | ----------------------------------------- |
| `src/middleware.ts`              | Supabase session refresh on every request |
| `src/lib/supabase/client.ts`     | Browser-side Supabase client              |
| `src/lib/supabase/server.ts`     | Server-side Supabase client (cookies)     |
| `src/app/auth/callback/route.ts` | OAuth code exchange                       |
| `src/app/layout.tsx`             | Root layout with Header                   |
| `src/globals.css`                | Tailwind v4 theme configuration           |

## Adding Pages

Create a file at `src/app/<route>/page.tsx`. For protected pages, check auth with `createClient()` from `@/lib/supabase/server`.

## Styling

Tailwind CSS v4 uses CSS-first configuration. Custom theme variables are defined in `src/globals.css` using `@theme inline`. There is no `tailwind.config.ts`.
