prakharg69/REAL-time-POS ? reverse-engineered prompt

Build me a simple real time point of sale app with a frontend and a backend.

I want a clean screen where a cashier can add items to a cart, update quantities, remove items, and see the total update right away. The app should let me search or pick products, complete a sale, and show a basic receipt or order summary after checkout. It should also keep the backend and frontend connected so changes can show up in real time without refreshing.

Make it feel like a small working store system that is easy to use and looks decent on desktop. If anything is unclear, use sensible defaults and keep the setup straightforward. Look up current docs online if you need to.
