Supabase setup (Mova Store)

1. Create a project at supabase.com.
2. Copy Project URL and anon public key into .env.local:
   • NEXT_PUBLIC_SUPABASE_URL
   • NEXT_PUBLIC_SUPABASE_ANON_KEY
3. Configure Admin access in .env.local:
   • Set NEXT_PUBLIC_ADMIN_EMAILS to your email (e.g. NEXT_PUBLIC_ADMIN_EMAILS=admin@example.com). Multiple emails can be comma-separated.
   • AuthContext reads this variable via isAdminEmail (lib/env.ts), and components/AdminGuard.jsx uses it to gate all /admin routes. If left unset, isAdmin defaults to false and authenticated users will be blocked with an "Access Denied" error when attempting to reach the admin catalog panel.
4. In the SQL editor, run schema.sql.
5. Auth → Providers: enable Email (and Google if you want OAuth).
6. Auth → URL Configuration: add http://localhost:3000/** (and your production URL).
7. Restart npm run dev.

Products live in the products table; images in the public products storage bucket.
