## Overview

This is a React/Express storefront with account signup and login, a product catalog, token-protected cart and checkout endpoints, and an admin user-management interface. The admin workflow supports searching and editing users, plus CSV/JSON/PDF import and CSV export; imports are parsed and persisted by the user controller. The sampled cart handlers return order responses without persistent cart or order storage. The README is empty, and frontend product/cart wiring and several page implementations were not sampled, so those connections are omitted.
