+ * - Its `droppableId` must stay STABLE while mounted (anchored to a formId,
+ *   never a positional index): @hello-pangea/dnd does not support changing
+ *   ids on mounted droppables/draggables, which silently breaks them.
+ * - `type="RECIPIENT"` already scopes it to recipient-row drags, and
+ *   `isDropDisabled` must not be toggled based on the active drag, as
+ *   @hello-pangea/dnd snapshots it at drag start (before state updates land).
