ornobfour-jpg/e-commerce-web — reverse-engineered prompt

Build me a clean ecommerce web app for a small online store. I want it to feel modern, fast, and easy to use on both phone and desktop.

People should be able to browse sample products, search or filter them, open a product details page or modal, add items to a cart, change quantities, remove items, and see the total clearly. Add a simple checkout flow that does not take real payments, just collects basic customer info and shows an order confirmation.

Since this app is connected to Gemini, include a simple AI shopping helper that can answer product questions and suggest items based on what the shopper asks. Use the Gemini API key from the environment file.

Please make it look polished with good spacing, empty states, loading states, and sensible sample product data. Keep the code easy to run locally with npm install and npm run dev. Look up current docs online if you need to.
