## Overview

This is a minimal healthcare-startup landing page with an Express backend. The browser renders a welcome screen, opens a contact form after five seconds, and logs submissions locally; the form does not send data to the backend. The backend exposes a health-check route and accepts Socket.IO connections. The excerpts show no integration between the client and server, so none is drawn.

Main entry points: [`client/src/index.js`](https://github.com/hamzaahmd/healthcare-hub/blob/main/client/src/index.js) (React entry), [`client/src/App.js`](https://github.com/hamzaahmd/healthcare-hub/blob/main/client/src/App.js) (Welcome and contact form)
