## Improvements in NiceGUI

### 1. People Mentioned ✨
The NiceGUI version includes a "People Mentioned" section that the legacy UI doesn't have:
```python
if email['extraction'].get('people'):
    with ui.column().classes('flex-1'):
        ui.label('People Mentioned').classes('text-xs text-gray-400 font-bold uppercase mb-2')
        with ui.row().classes('flex-wrap gap-2'):
            for person in email['extraction']['people']:
                ui.label(person).classes('px-2 py-1 bg-white/5 rounded text-xs text-gray-400')
```

### 2. Better Icon Integration
The download button uses inline SVG for better rendering:
```python
ui.html('<svg xmlns="http://www.w3.org/2000/svg" class="w-4 h-4" fill="none" viewBox="0 0 24 24" stroke="currentColor">
    <path stroke-linecap="round" stroke-linejoin="round" stroke-width="2" d="M4 16v1a3 3 0 003 3h10a3 3 0 003-3v-1m-4-4l-4 4m0 0l-4-4m4 4V4" />
</svg>')
```

### 3. Cleaner Code Structure
The NiceGUI version uses context managers for better organization:
```python
with ui.dialog() as dialog, ui.card().classes('w-full max-w-4xl max-h-[90vh] overflow-hidden'):
    with ui.row().classes('w-full justify-between items-start p-4 border-b border-white/10'):
        # Header content
    
    with ui.column().classes('flex-1 overflow-y-auto p-6 gap-6'):
        # Scrollable content
```

### 4. Consistent Styling
All panels use the same color scheme:
- Classification: Blue (`bg-blue-900/20 border-blue-500/20`)
- System Info: Purple (`bg-purple-900/20 border-purple-500/20`)
- Extraction: Indigo (`bg-indigo-900/20 border-indigo-500/20`)
