Web App (@foundry/web)

The web app is a Next.js 15 application using the App Router, Tailwind CSS v4, and Supabase for authentication.

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

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.
