BhavyaSailor/product_app ? reverse-engineered prompt

Build me a simple product management app with a clean frontend and a backend that can store and update products.

I want a page where I can see a list of products, add a new product, edit an existing one, delete one, and view basic details like name, price, description, and stock. Make it feel polished and easy to use on desktop and mobile.

Please set up both sides so they work together smoothly, with the frontend talking to the backend through normal API calls. Use sensible defaults, basic form validation, and make sure errors are handled nicely so the app does not just break if something goes wrong.

If you need to check current docs or best practices for anything, feel free to look them up. Keep the code simple and organized so it is easy for me to extend later.
