@Component({

  standalone: true,
  template: `
    <h3>{{ title }}</h3>                      <!-- interpolation -->
    <button [disabled]="busy">Save</button>   <!-- property binding -->
    <button (click)="busy = !busy">Toggle</button> <!-- event binding -->
    <input [(ngModel)]="title" />             <!-- two-way (needs FormsModule) -->
