## Overview

This is a browser-based storefront. Shoppers browse externally fetched products, filter or sort them, then add items to a locally persisted cart or wishlist; the cart supports quantity changes and a simulated checkout. Separate pages support signup, login, and password reset, while shared UI code handles theme, navigation, and logout. The README is empty, and the sampled source does not show page script wiring; the graph therefore omits uncertain page-to-script links and treats the Firebase files as a separate optional auth path.

Main entry points: [`scripts/app.js`](https://github.com/mounikay845-source/ecommerce-frontend/blob/main/scripts/app.js) (Catalog and search), [`scripts/cart.js`](https://github.com/mounikay845-source/ecommerce-frontend/blob/main/scripts/cart.js) (Cart and wishlist), [`scripts/forgot.js`](https://github.com/mounikay845-source/ecommerce-frontend/blob/main/scripts/forgot.js) (Reset-link generation), [`scripts/session.js`](https://github.com/mounikay845-source/ecommerce-frontend/blob/main/scripts/session.js) (Auth session watcher)
