In this episode, we’ll integrate **React Router** into our app to allow page navigation between **Home**, **Cart**, and **Login**.

In this episode, we'll build the **Home page** of the e-commerce site. We'll create a **product card component**, use **dummy JSON data**, and style everything using **Tailwind CSS**.
