  # Note on Supabase:
  # This setup binds the Next.js app to your local machine. 
  # If you are running the local Supabase CLI (`npx supabase start`), 
  # you should set your NEXT_PUBLIC_SUPABASE_URL in `.env.local` to 
  # `http://host.docker.internal:54321` (or whichever port your local Supabase uses)
  # so the Docker container can reach it.
