We couldn't reach Supabase or the seed data isn't in place. To fix this:

1. Create a Supabase project and run the seed SQL (the one withmachines,users,tickets,refunds).
2. Replace the xxx values in .env.local with your real keys.
3. Restart the dev server.

Reason: SUPABASE_SERVICE_ROLE_KEY is the anon or authenticated key. Use the service_role secret from Supabase → Project Settings → API (never expose it to the browser).
