Variant preview integration

Files Modified:

widget-builder-workspace.component.ts - Integration logic

Key Features:

✅ Design → Preview synchronization
✅ Variants → Preview integration
✅ Property updates → Live preview
✅ Flash persistence for all state
✅ Smooth animations
✅ Error handling

📊 Technical Implementation

Dependencies Used

@angular/cdk/drag-drop - Drag and drop functionality
@storage-system - Flash persistence
Angular Signals - Reactive state management
Computed signals - Derived state

Architecture Patterns

Signal-based reactivity - All state managed with signals
Computed values - Efficient derived state
Effect-based sync - Design → Preview synchronization
Flash persistence - Auto-save all user state
Component isolation - Each panel is independent

Performance Optimizations

ChangeDetectionStrategy.OnPush - All components
Computed signals - Efficient recalculation
Lazy loading - Components load on demand
Flash persistence - Minimal storage writes
