app.py

I notice your request just says "no" - I'm not sure what you'd like me to modify. Looking at your current code, it appears to be a **Veo-3 Video Generator** application with:

- Text-to-video and image-to-video generation
- Demo mode (simulated) and live API mode
- Modern Gradio 6 UI with custom theme

Could you please clarify what changes you'd like? For example:
- **Remove** a feature?
- **Add** new functionality?
- **Fix** something that's not working?
- **Simplify** the code?
- **Change** the UI layout?
- Something else?

Please provide more details about what "no" refers to, and I'll modify the code accordingly.
