Setup needed

Connect the web app to Supabase.

The public landing page works without credentials, but admin login needs the client-side Supabase variables before sign-in can work.

  1. Set `NEXT_PUBLIC_SUPABASE_URL`.
  2. Set `NEXT_PUBLIC_SUPABASE_ANON_KEY`.
  3. Set `LOOKBOX_ADMIN_EMAILS` with allowed admin emails.
