ShopSmart — Responsive E-commerce Frontend

ShopSmart is a responsive e-commerce frontend built from a Figma design and focused on implementing a complete shopping experience rather than a simple product grid.

The application includes product search and filtering, category/brand/price filters, a persistent cart, validated checkout, order history, incremental loading, loading and retry states, and PDF invoice generation with Persian font support. Product data is provided through the DummyJSON API, while cart and order data are persisted in localStorage.
