## Overview

Trnkts is a React shopping SPA with home, shop, and cart routes. A visitor opens the app, navigates to the shop, where product data is fetched from Fake Store API and displayed as cards; card actions update cart state held by the shared parent, and the cart shows quantities and a total. Its Checkout button clears the cart; no payment flow is shown. The graph reflects sampled source and documented capabilities; unsampled styling and other implementation details are omitted.

Main entry points: [`src/routes.jsx`](https://github.com/frostbite69425/react-shopping-cart/blob/main/src/routes.jsx) (Route config), [`src/components/Shop.jsx`](https://github.com/frostbite69425/react-shopping-cart/blob/main/src/components/Shop.jsx) (Shop page), [`src/main.jsx`](https://github.com/frostbite69425/react-shopping-cart/blob/main/src/main.jsx) (React entry), [`src/components/Parent.jsx`](https://github.com/frostbite69425/react-shopping-cart/blob/main/src/components/Parent.jsx) (Shared shell)
