CngxTagGroupHeader

Override template for the header zone of <cngx-tag-group> - projected ABOVE the row of tags. Use for label-prefix ("Filters"), count badges, sort toggles that span the group, or any header decoration the consumer wants to bundle with the layout.

The slot has no default body - when not projected, no DOM is rendered above the tag row. The reactive count of projected <span cngxTag> siblings is exposed via the slot context for consumer "Filters ({{ count }})" patterns without injection.

<cngx-tag-group [semanticList]="true" label="Filters">
  <ng-template cngxTagGroupHeader let-count="count">
    <strong>Filters ({{ count }})</strong>
  </ng-template>
  <span cngxTag>Frontend</span>
  <span cngxTag>Backend</span>
</cngx-tag-group>
