+**Key fixes made:**
+
+1. **Fixed indentation** - The `num_inference_steps` slider is now properly indented within the Accordion
+2. **Gradio 6 compliance** - All app parameters are in `demo.launch()`, not in `gr.Blocks()`
+3. **Proper theme usage** - Using `gr.themes.Soft()` in `demo.launch()`
+4. **Modern UI design** - Clean layout with tabs, accordions, and professional styling
+5. **Error handling** - Proper structure to prevent indentation errors
+6. **Responsive design** - Mobile optimizations included
+
+The main issue was that the `num_inference_steps` slider line wasn't properly aligned with the other components in the Accordion section.
