## Type System Updates

### DeploymentStatus (Changed from Enum to Struct)

**Previous** (Enum):
```rust
pub enum DeploymentStatus {
    Pending,
    DetectingPlatforms,
    // ...
}
```

**Current** (Struct):
```rust
pub struct DeploymentStatus {
    pub current_step: String,
    pub progress: f64,           // 0.0 to 1.0
    pub completed_steps: usize,
    pub total_steps: usize,
    pub is_complete: bool,
    pub has_errors: bool,
}
```

**Rationale**: Struct provides more granular progress tracking needed for the deployment screen's progress bar and step counter.

---

## UI Design Patterns

### Layout Pattern
All screens follow a consistent 4-section vertical layout:
1. **Title** (3-5 lines) - Screen heading with icon
2. **Main Content** (flexible) - Primary interactive area
3. **Details/Info** (optional) - Additional information panel
4. **Instructions** (3 lines) - Keyboard shortcuts

### Color Scheme
- **Cyan**: Primary accent, selected items, titles
- **Green**: Success states, enabled items, confirmations
- **Red**: Errors, warnings, destructive actions
- **Yellow**: Highlights, recommended items, intermediate states
- **Gray**: Disabled items, secondary text
- **White**: Default text

### Icons
- 🚀 - Deployment/Launch
- 🔍 - Detection/Search
- 📦 - Mode/Package
- 🔧 - Services/Configuration
- 📋 - Review/Summary
- ✅ - Success
- ❌ - Failure
- ⚠️ - Warning
- 🌐 - Network/Access
- 📝 - Steps/Actions
- 📚 - Documentation

### Navigation
- Consistent keyboard shortcuts across all screens
- Clear visual feedback for selected items
- Intuitive back/forward flow
- Quit option always available

---

## Compilation Status

**Build Command**:
```bash
cd provisioning/platform/installer
cargo build
