amritmaurya1504/Restaurant_POS_System — reverse-engineered prompt

Build me a restaurant POS system for a small dine in restaurant. I want staff to log in, take table orders, update order status, manage reservations, create bills, and collect online payments through Razorpay. Admins should be able to manage users, menu items, basic inventory, and see orders and payments in a clean dashboard.

Please make it a full stack app with a React frontend and a Node, Express, MongoDB backend. Use secure login with different access for admin, staff, and normal users. The UI should feel like a modern point of sale screen, with tables, order cards, cart totals, invoice details, and clear actions for confirming, preparing, serving, and completing orders.

Add realistic sample data so I can test it right away. Include setup instructions, environment variables, and seed data if needed. Look up current docs online if you need to, especially for Razorpay and authentication best practices.
