fctanu/MyPOS — reverse-engineered prompt

Build me a new web based POS app for a small shop using this existing project. There isn’t much README guidance, so use the current code and folders as the starting point and keep the scope practical.

I want a cashier to be able to open the app, search or tap products, add them to a sale, adjust quantities, remove items, see the total clearly, choose a payment method, enter cash received, and finish the sale with a simple receipt view. Please also include a basic way to manage products and view recent sales so it feels like a real working first version, not just a mockup.

Make the interface clean, fast, and easy to use on a counter screen. Use simple sample data if the backend is not ready, but structure it so real API calls can be plugged in later. Make sure it runs locally without confusing setup steps.
