🎯 KEY INNOVATIONS

1. Dual-Mode Styling:

Theme Mode: Use design system tokens
Manual Mode: Explicit pixel values
Hybrid Mode: Mix both seamlessly
Auto-Upgrade: Theme → Hybrid when user overrides

2. 6-Layer Hierarchy:

Clear Priorities: 100-600 scale
Context-Aware: Layers activate based on state/breakpoint
Conflict Resolution: Highest priority wins, always
Full History: Every change tracked

3. Platform-Agnostic:

JSON Storage: All styles as structured data
Multi-Platform: Export to Web/RN/Flutter/Native
AI-Ready: Rich metadata for training
Future-Proof: Easy to add new platforms

🌟 REAL-WORLD FLOW

User Journey:

1. User opens editor
   ↓
2. Selects button widget
   ↓
3. Property panel loads
   - Resolver registered: btn-001
   - Current values resolved from hierarchy
   - Display: backgroundColor = #3b82f6 (from theme)
   ↓
4. User clicks color picker
   ↓
5. User selects #FF5722
   ↓
6. Resolver called:
   setPropertyValue('btn-001', 'backgroundColor', '#FF5722', {
     state: 'default',
     breakpoint: 'desktop',
     userEditing: true  // ← KEY: Creates user override layer
   })
   ↓
7. Resolver processes:
   - Detects userEditing: true
   - Creates Layer 5 (User Override, priority 500)
   - Converts theme mode to hybrid mode
   - Preserves all other theme tokens
   - Rebuilds layer stack
   - Emits StyleChangeEvent
   ↓
8. Widget re-renders:
   - Background: #FF5722 (User override, Layer 5)
   - Padding: 12px (Theme, Layer 1)
   - Font: 16px (Theme, Layer 1)
   - Radius: 8px (Theme, Layer 1)
   ↓
9. User switches to mobile preview
   ↓
10. User sets width to '100%'
    ↓
11. Resolver called:
    setPropertyValue('btn-001', 'width', '100%', {
      state: 'default',
      breakpoint: 'mobile',  // ← Mobile breakpoint
      userEditing: true
    })
    ↓
12. Resolver processes:
    - Creates Layer 4 (Responsive - Mobile, priority 400)
    - Only active when breakpoint = 'mobile'
    ↓
13. Desktop view:
    - Width: auto (no mobile layer active)
    ↓
14. Mobile view:
    - Width: 100% (mobile layer active)
    ↓

✅ RESULT: Perfect harmony, no competition!

Easy debugging
Full history tracking

✅ User Experience:

Intuitive property panel
Predictable results
Undo/redo support
Visual feedback

✅ AI-Ready:

Rich metadata
Pattern learning
Change tracking
Intent capture

🚀 NEXT PHASE

Phase 3: Property Panel Integration

Step 1: Inject Resolver:

export class PropertiesPanelComponent {
  private resolver = inject(StyleHierarchyResolverService);
}

Step 2: Register Widgets:

loadWidget(widgetId: string): void {
  const config = this.getWidgetStyleConfig(widgetId);
  this.resolver.registerWidget(widgetId, config);
}

Step 3: Use Resolver for Get/Set:

// Get current value
const bgColor = this.resolver.getPropertyValue(
  widgetId,
  'backgroundColor',
  this.getContext()
);

// Set new value
this.resolver.setPropertyValue(
  widgetId,
  'backgroundColor',
  newValue,
  this.getContext()
);

Step 4: Display Conflicts:

const conflicts = this.resolver.getConflicts(widgetId, context);
if (conflicts.length > 0) {
  // Show warning badge
  this.showConflictWarning(conflicts);
}

💡 KEY LEARNINGS

1. Clear Hierarchy Prevents Competition:

Without priorities, styles compete
With priorities, there's always a clear winner
Context-aware activation prevents unintended application

2. Flexibility Requires Structure:

Theme mode for consistency
Manual mode for control
Hybrid mode for best of both
Auto-upgrade when needed

3. History Enables Undo:

Track every change
Store before/after
Enable reset to any point
Learn from user patterns

4. Platform-Agnostic is Essential:

Web won't be the only target
Mobile apps coming
Desktop apps possible
Store as JSON, convert anywhere
