## π¨ Customization Guide
### Change Chatbot Behavior
Edit `system_prompt.txt` β modify identity, rules, tone, or knowledge sources.
### Update Website Info

```
### Change UI Theme
In `public/index.html`, update CSS gradient colors:
```css
background: linear-gradient(135deg, #YOUR_COLOR_1 0%, #YOUR_COLOR_2 100%);
```
### Integrate Real LLM
In `server.js`, replace `generateMockResponse()` with code from `llm-integration.js`.
### Connect Real MCP Server
In `server.js`, update:
```javascript
const mcp = new MCPClient('http://your-mcp-server:3001');
```
