+/**
+ * CardLayouts are used within {@link OO.ui.IndexLayout index layouts} to create cards that users can select and display
+ * from the index's optional {@link OO.ui.TabSelectWidget tab} navigation. Cards are usually not instantiated directly,
+ * rather extended to include the required content and functionality.
+ *
+ * Each card must have a unique symbolic name, which is passed to the constructor. In addition, the card's tab
+ * item is customized (with a label) using the #setupTabItem method. See
+ * {@link OO.ui.IndexLayout IndexLayout} for an example.
