Mini React-Tailwind E-Commerce App

I need a compact yet polished web storefront built entirely with React and Tailwind CSS. The shop will sell physical goods, so clear product-category browsing, a tidy shopping-cart flow, and a fast checkout are essential.

Core features to include
• Product catalogue organised by categories
• Product detail pages that surface user reviews
• Add-to-cart, update, and remove functionality with a persistent cart view
• Secure credit/debit-card payment at checkout (gateway of your choice, as long as it supports card payments and can be swapped later)

Please deliver clean, well-commented React components, Tailwind-ready styling, and any minimal backend or mock API hooks needed for product, review, and order data so I can plug in our own service later. A short README with setup and build steps will round it off.
