## Overview

This is a small React storefront: users browse a hard-coded product list and can trigger an add-to-cart alert. Its service worker adds asset caching, a placeholder background-sync routine, and push-event notifications. The sync routine does not persist or transmit orders, and the UI’s PUSH_TEST message has no matching message handler in the sampled worker; those behaviors are not represented as completed workflows.

Main entry points: [`public/service-worker.js`](https://github.com/vaishnavi21m/ecommerce-ui/blob/main/public/service-worker.js) (Service worker), [`src/App.js`](https://github.com/vaishnavi21m/ecommerce-ui/blob/main/src/App.js) (Product storefront), [`src/index.js`](https://github.com/vaishnavi21m/ecommerce-ui/blob/main/src/index.js) (React entry)
