This modified application:
- **Uses Gradio 6 syntax** with all parameters in `demo.launch()`
- **Includes only the theme switcher** - no chatbot components
- **Maintains the professional theme system** with Soft, Glass, Monochrome, and Base themes
- **Follows the Gradio 6 pattern**: `gr.Blocks()` has NO parameters, everything goes in `demo.launch()`
- **Provides a clean, modern interface** with the theme dropdown and apply button
- **Includes the required attribution** linking to anycoder

The key changes:
1. **Removed chatbot components** (Chatbot, Textbox for messages)
2. **Kept the theme switcher functionality** with dropdown and apply button
3. **Uses proper Gradio 6 event handling** with `api_visibility="public"`

The application now focuses purely on demonstrating the dynamic theme switching capability that Gradio 6 provides with its enhanced theming system.
