4. Set up Supabase database

   # Run the database schema
   psql -h your-supabase-host -U postgres -d postgres -f scripts/create-database.sql
   
   # Seed with demo data
   psql -h your-supabase-host -U postgres -d postgres -f scripts/seed-demo-data-final.sql

5. Start the development server

   pnpm dev
