+ *  - A **display-type toggler** (flat vs. overlap layout)
+ *
+ * Depending on whether the parent is a VisualDeckEditorWidget, this widget can mirror the
+ * original group by checkbox from the main deck editor UI to maintain synchronization.

+ * It emits signals whenever the grouping criterion, sorting criteria, or display mode changes.
