+Two IIFE builds for script tag usage:
 
-```html
+| Build | File                 | Description                      |
-<script src="page-agent.js?model=gpt-4"></script>

+| Demo  | `page-agent.demo.js` | Auto-init with built-in test API |
+| Full  | `page-agent.js`      | Exposes `PageAgent` class only   |
 
-Query params configure `PageAgentConfig` in `src/umd.ts`.
+Demo build supports query params (e.g., `?model=gpt-4&lang=en-US`).
