 * ### Rerender zone-less app on route changes
 *
 * ```ts
 * @Component({
 *   selector: 'app-root',
 *   template: '<router-outlet>',
 *   // 👇 `RenderScheduler` is provided at the component level
 *   providers: [RenderScheduler],
 *   changeDetection: ChangeDetectionStrategy.OnPush,
 * })
 * export class AppComponent implements OnInit {
 *   constructor(
 *     private readonly router: Router,
 *     private readonly renderScheduler: RenderScheduler
 *   ) {}
 *
 *   ngOnInit(): void {
 *     this.router.events
 *       .pipe(filter((e) => e instanceof NavigationEnd))
 *       .subscribe(() => this.renderScheduler.schedule());
 *   }
 * }
 * ```
 *
 * ### Rerender component on interval
 *
 * ```ts
 * @Component({
 *   selector: 'app-interval',
 *   template: '{{ elapsedTime }}ms',
 *   // 👇 `RenderScheduler` is provided at the component level
 *   providers: [RenderScheduler],
 *   changeDetection: ChangeDetectionStrategy.OnPush,
 * })
 * export class IntervalComponent implements OnInit {
 *   elapsedTime = 0;
 *
 *   constructor(private readonly renderScheduler: RenderScheduler) {}
 *
 *   ngOnInit(): void {
 *     setInterval(() => {
 *       this.elapsedTime += 1000;
 *       this.renderScheduler.schedule();
 *     }, 1000);
 *   }
 * }
