Testing Checklist

- Add an item twice; quantity is 2.
- Change quantity; total recalculates.
- Refresh page; demo cart remains on this device.
- Empty cart cannot create an order.
- Invalid email is rejected by the form.
- Submit valid demo order; summary contains items and total.
- Check layout on narrow mobile and keyboard navigation.
Important: This is a browser learning simulation, not a production e-commerce platform. Real payments, tax, authentication, server orders, stock management and privacy compliance require additional development and testing.
