 **Usage:**
 ```typescript
-import { DeesDemoWrapper } from '@design.estate/dees-wcctools/demoTools';
+import * as demoTools from '@design.estate/dees-wcctools/demotools';
 
 // In your demo function:
 demo: () => html`

-    // Do something with the rendered element
-    element.setAttribute('data-demo', 'true');

 **Features:**
 - Wraps demo elements without affecting layout (uses `display: contents`)
-- Provides access to the rendered element instance after mounting
+- Provides access to ALL slotted elements via HTMLCollection after mounting
 - Supports async operations in runAfterRender callback
-- Automatically handles timing to ensure element is fully rendered
