/**
 * Custom sortable strategy where anchored items act as immovable rocks.
 *
 * The default `verticalListSortingStrategy` cascades every item between
 * activeIndex and overIndex by one row. That's wrong when some slots are
 * anchored (completed/past) — those should stay put while only the movable
 * slots reshuffle around them.
