## Overview

LOOPS is a browser-based storefront. Shoppers browse and filter products, add items to a cart, adjust quantities, review shipping and totals, then enter delivery details and choose payment to create an order confirmation. The sampled script shows these behaviors are client-side only; no backend payment or order service is evident. The HTML and styling are represented from the file tree, but their contents were not sampled, so specific UI wiring is not asserted.

Main entry points: [`index.html`](https://github.com/yyunii/web-loops/blob/main/index.html) (Storefront page), [`script.js`](https://github.com/yyunii/web-loops/blob/main/script.js) (Cart totals), [`style.css`](https://github.com/yyunii/web-loops/blob/main/style.css) (Page styling)
