CngxTimelineRetryButton

Just the retry control inside the default error surface, for apps that want their own button component without rewriting the error copy.

Whatever renders here has to be operable: the library ships no button component, so a consumer template is responsible for its own type, accessible name and click wiring.

<ng-template cngxTimelineRetryButton let-retry>
  <button type="button" (click)="retry()">Try again</button>
</ng-template>
