Supabase: dashboard plus two keys

No MCP, no CLI. The user copies in the browser and pastes in the terminal.

1. Create the project (user, in the browser)

1. https://supabase.com/dashboard → New project
2. Name it after the app, any password (no need to save it, the app does not use it), Region Northeast Asia (Seoul).
3. Provisioning takes one to two minutes. Prepare step 2 meanwhile.

2. Two keys into .env.local

Dashboard, left sidebar, Project Settings → API:

• Project URL → NEXT_PUBLIC_SUPABASE_URL
• anon public key → NEXT_PUBLIC_SUPABASE_ANON_KEY
