#### `src/components/context-menu/context-menu.component.ts`
- **Standalone Angular component** with full right-click menu functionality
- **8-color palette** for folder categorization
- **Smooth animations** (fade-in + scale 0.95 → 1)

## 🚀 How to Use

### For Users
1. Navigate to **Folders** section in sidebar
2. **Right-click** on any folder
3. Select an action from the menu
4. Confirm if prompted
5. Action completes with notification

### For Developers

#### View the Menu
```bash
npm run dev
# Navigate to Folders → Right-click any folder
```

#### Build the Project
```bash
npm run build
# ✅ Build successful with no errors
```

#### Customize Colors
Edit `src/components/context-menu/context-menu.config.ts`:
```typescript
export const CONTEXT_MENU_COLORS: ContextMenuColorConfig[] = [
  { hex: '#0ea5e9', name: 'Sky Blue', description: '...' },

## 💾 Data Persistence

### Folder Colors Storage
Colors are saved in browser's localStorage:

```json
{
  "folderColors": {
    "path/to/folder1": "#0ea5e9",
    "path/to/folder2": "#ef4444",
    "path/to/folder3": "#22c55e"
  }
}
```

**Persistence:**
- ✅ Automatic save on color selection
- ✅ Automatic load on component init
- ✅ Survives page refresh
- ✅ Per-browser storage (not synced across devices)

---

## 🎨 Color Palette

| Color | Hex | Name | Use Case |
|-------|-----|------|----------|
| 🔵 | #0ea5e9 | Sky Blue | Default, general purpose |
| 🔵 | #3b82f6 | Blue | Important folders |

## 🔄 Integration Roadmap

### Phase 1: UI Complete ✅
- [x] Context menu component
- [x] File explorer integration
- [x] Color palette
- [x] Animations & positioning
- [x] Documentation

### Phase 2: VaultService Integration ⏳

- [ ] Duplicate folder
- [ ] Create new page
- [ ] Delete folder
- [ ] Delete all pages
- [ ] Estimated effort: 2-3 hours

### Phase 3: Enhancements (Future)

- [ ] Custom icons
- [ ] Drag & drop
- [ ] Folder tagging
- [ ] Bulk operations

## 🐛 Known Limitations

1. **Actions are placeholders** - Need VaultService implementation
2. **No keyboard navigation** - Only ESC to close (can be enhanced)
3. **No submenu support** - Single-level menu only
4. **No drag & drop** - Separate feature
5. **No bulk operations** - Single folder at a time
