{
  path: '/clients/:id/detail',
  name: 'ClientDetailNew',
  component: () => import('@/views/pages/CRM/ClientDetailNew.vue')
}
```

### Replace Old ClientDetail
To use this as the main client detail page:

```javascript
// Change existing route
{
  path: '/clients/:id',
  name: 'ClientDetail',
  component: () => import('@/views/pages/CRM/ClientDetailNew.vue')  // Changed from ClientDetails.vue
}
```

## Component Structure

### Template Sections
1. **Header** - Back button to clients list
2. **Loading State** - Spinner while fetching data
3. **Error State** - Alert for errors
4. **Main Content** 
   - Left: Client card + navigation
   - Right: Tab content

### Script Features
```javascript
// Reactive data
const activeTab = ref('overview')  // Current tab
const clientAvatar = ref(null)     // Client logo/avatar
const contacts_client = ref([])    // Client contacts

// Methods
getInitials(name)        // Generate initials from name
formatAddress(client)    // Format full address string
triggerFileInput()       // Open file selector
handleAvatarUpload()     // Handle logo upload
```

### Styling Features
- **Sticky sidebar** - Stays visible when scrolling
- **Active tab highlighting** - Gradient background
- **Smooth transitions** - Hover effects
- **Responsive design** - Works on mobile
- **Clean cards** - Soft shadows and borders

## Design Principles

### Color Scheme
- **Primary Actions**: Gradient purple-pink (`#7928ca` to `#ff0080`)
- **Success**: Green for active status and badges
- **Info**: Blue for contact info
- **Warning**: Yellow for business info
- **Danger**: Red for inactive status

### Typography
- **Headers**: Bold, clear hierarchy
- **Body**: `text-sm` for readability
- **Labels**: Uppercase with spacing

### Icons
Using Font Awesome:
- 📊 `fa-eye` - Overview
- ℹ️ `fa-info-circle` - Information
- 👥 `fa-users` - Contacts
- 📍 `fa-map-marker-alt` - Address
- 📝 `fa-sticky-note` - Notes

## Avatar/Logo Upload

### Current Implementation
```javascript
handleAvatarUpload(event) {
  const file = event.target.files[0];
  if (file) {
    const reader = new FileReader();
    reader.onload = (e) => {
      clientAvatar.value = e.target.result;
      // TODO: Upload to server
    };
    reader.readAsDataURL(file);
  }
}
```

### TODO: Connect to Backend
To implement server upload:

```javascript
const handleAvatarUpload = async (event) => {
  const file = event.target.files[0];
  if (!file) return;
  
  const formData = new FormData();
  formData.append('avatar', file);
  formData.append('client_id', clientStore.currentClient.id);
  
  try {
    const response = await api.post('/clients/upload-avatar', formData, {
      headers: { 'Content-Type': 'multipart/form-data' }
    });
    
    clientAvatar.value = response.data.avatar_url;
    // Update store
    await clientStore.fetchClient(client_id);
  } catch (error) {
    console.error('Upload failed:', error);
  }
};
```

## Comparison: Old vs New

### Old Design
- Single page layout
- All info visible at once
- No image/avatar support
- Basic styling
- No tab organization

### New Design ✨
- Modern tabbed interface
- Client avatar/logo with upload
- Sticky sidebar navigation
- Card-based organization
- Better mobile responsive
- Visual hierarchy
- Quick stats
- Empty states
- Badge indicators

## Customization

### Change Tab Order
```vue
<!-- Reorder nav items in the sidebar -->
<ul class="nav nav-pills flex-column">
  <li class="nav-item">
    <a @click="activeTab = 'your-tab'">...</a>
  </li>
</ul>
```

### Add New Tab
1. Add nav item in sidebar
2. Add content section with `v-show`
3. Update `activeTab` ref

```vue
<!-- Nav item -->
<li class="nav-item pt-2">
  <a
    class="nav-link"
    :class="{ active: activeTab === 'documents' }"
    @click="activeTab = 'documents'"
  >
    <i class="fas fa-file me-2"></i>
    <span class="text-sm">Documents</span>
  </a>
</li>

<!-- Content -->
<div v-show="activeTab === 'documents'" class="card">
  <div class="card-header pb-0">
    <h6 class="mb-0">Documents</h6>
  </div>
  <div class="card-body">
    <!-- Your content -->
  </div>
</div>
```
