Local setup

1. Copy .env.example to .env.local and configure DATABASE_URL, BETTER_AUTH_SECRET, BETTER_AUTH_URL, and BLOB_READ_WRITE_TOKEN.
2. Install dependencies with npm install.
3. Create the schema with npm run db:migrate.
4. Set INITIAL_ADMIN_EMAIL, INITIAL_ADMIN_NAME, and INITIAL_ADMIN_PASSWORD, then run npm run db:seed.
5. Start with npm run dev and open http://localhost:3000.

The public storefront uses the bundled catalog and local /public/products images when DATABASE_URL is absent. Authentication, checkout, account, and admin requests require PostgreSQL and report a configuration error until it is configured.
