santosh-sunuwar-mukhiya/product_catalog ? reverse-engineered prompt

Build me a simple product catalog app where people can browse a list of products, see basic details for each one, and add new products from a form.

I want it to be a full stack app with a clean frontend and a backend that stores the data, so the products stay saved and can be loaded again later. Keep the design simple and easy to use, with a main page that shows the catalog and a way to view or edit a product if needed. Make it feel like a real small business inventory or store catalog app.

Please set up the project so the frontend and backend work together smoothly, and make sure I can run it locally without too much setup. If you need to check current docs or best practices for any library details, feel free to look them up online.
