+	 * The left-gutter grip is `draggable`; grabbing it starts an HTML5 drag
+	 * that carries the block's top-level index on a private MIME type
+	 * (`WORDS_BLOCK_DRAG_TYPE`). This controller listens on the contenteditable,
+	 * paints a horizontal indicator at the nearest inter-block seam during the
+	 * drag, and on drop repositions the block via the engine's `moveBlockTo`
+	 * command.
+	 *
+	 * Native text drag-drop is untouched: every handler bails unless the drag
+	 * carries our private type, so selecting text and dragging it still goes
+	 * through the browser's default path.
+	 *
+	 * Block detection mirrors the gutter exactly — top-level blocks are the
+	 * content's direct `[data-words-node='block']` children, and `fromIndex`
+	 * (written by the grip) indexes the same array. Reorder is therefore
+	 * top-level only; nested blocks (inside columns / cells) are not draggable.
