## 🚀 Next Steps (Future Enhancements)

Once the `calendar-elements-ui` library components are available, replace placeholders with actual components:

1. **Import Components**: Add imports from `calendar-elements-ui`
2. **Replace Placeholders**: Swap placeholder divs with actual components
3. **Wire Up Inputs**: Connect component `@Input()` properties to signals
4. **Wire Up Outputs**: Connect component `@Output()` events to handlers
5. **Add Controls**: Add interactive controls for component properties
6. **Add Code Examples**: Show component usage code snippets

### Example Replacement Pattern

**Current (Placeholder):**
```html
<div class="demo-placeholder">
  <p class="placeholder-text">📅 Calendar Month View Component</p>
</div>
```

**Future (With Actual Component):**
```html
<calendar-month-view
  [events]="events()"
  [selectedDate]="selectedDate()"
  [showWeekends]="viewConfig().showWeekends"
  [firstDayOfWeek]="viewConfig().firstDayOfWeek"
  (dateSelect)="onDateSelect($event)"
  (eventClick)="onEventClick($event)"
/>
```
