Devansh0302/resturant-pos ? reverse-engineered prompt

Build me a modern restaurant POS web app for a small cafe or restaurant.

I want a clean, fast dashboard where staff can take orders, add items from a menu, update quantities, see a running total, and finish a sale. It should feel easy to use on a touchscreen, with a simple layout, nice colors, and a polished home screen for the brand. Include basic management pages for menu items and maybe tables or orders if that fits naturally.

Use the existing Next.js app structure and make it work end to end, with any data stored in a simple database setup if needed. Keep the app responsive, so it works well on desktop and tablet. If you need current docs or examples, look them up online and then build the thing cleanly.
