Integrate

> Adjust the Docker Compose commands/acronyms if you place `server` and `client` at different relative paths.

### 🚀 How to Integrate These Files:

1. **Create a new `server/` directory** in your repo and add:
   - `index.js`
   - `models/Message.js`
   - `models/User.js`
   - `auth.js`
   - `.env.example`
   - `Dockerfile`
   - `package.json`
   - (optional) `tests/` subfolder with `auth.test.js`
2. **Create a new `client/` directory** (or rename your existing front-end folder to `client/`) and add:
   - `index.html`
   - `app.js`
   - `style.css`
   - `Dockerfile`
   - `package.json` (optional)
3. Add `docker-compose.yml` at the repository root.
4. **Populate environment variables** in `/server/.env` (copy `.env.example` → `.env`).
5. **Install dependencies**:
   ```bash
   cd server
   npm install
   cd ../client
   npm install  # if using live-server for local dev
