CngxBreadcrumbItemAccessory

Structural slot for a per-crumb accessory inside the CngxBreadcrumbBar trail. Projected once, it renders inside every crumb's <li> (after the link), so a consumer can attach custom chrome or the router-driven siblings source that the declarative crumb.siblings field cannot reach (the bar stays free of @angular/router). When present, the slot wins globally over the declarative auto-render - one predictable owner of the accessory area.

<cngx-breadcrumb [items]="crumbs">
  <ng-template cngxBreadcrumbItemAccessory let-crumb>
    @if (crumb.siblings; as sibs) {
      <cngx-breadcrumb-siblings [siblings]="sibs" />
    }
  </ng-template>
</cngx-breadcrumb>
