/**
 * Custom keyboard coordinate getter for image-cloze-association's Tab-based placement.
 *
 * Tab/Shift+Tab cycle the dragged answer directly onto the next/previous enabled
 * droppable — a response container (`response-container-{index}`) or the choices pool
 * (`ica-board`) — sorted by on-screen position (top-to-bottom, then left-to-right),
 * since response containers are absolutely positioned over an image rather than laid
 * out as a simple list.
 *
 * Arrow keys are delegated to dnd-kit's own `defaultKeyboardCoordinateGetter`, leaving
 * the existing free-form arrow-key dragging behavior completely unchanged.
