## Overview

The Corner Cup is a café website with customer account, menu, cart, ordering, profile, and contact surfaces, plus an admin area. The documented runtime is a Node.js server. The sampled server code supports account and order APIs, contact-message submission, and admin order/message access backed by MongoDB; the sampled browser script submits contact forms and adjusts navigation. Other page-level interactions are not shown in the excerpts, so their API wiring is left unspecified.

Main entry points: [`server.js`](https://github.com/mkdole007/the-corner-cup/blob/main/server.js) (HTTP application), [`contact.html`](https://github.com/mkdole007/the-corner-cup/blob/main/contact.html) (Contact), [`app.js`](https://github.com/mkdole007/the-corner-cup/blob/main/app.js) (Browser behavior), [`login.html`](https://github.com/mkdole007/the-corner-cup/blob/main/login.html) (Login)
