The replica framed to a font-derived nominal width, so faces in wide lanes' interior masonry columns and narrow lanes dragged a preview of the wrong size and the cursor could sit over empty space beside it. CardFaceView's existing onGeometryChange now reports size, not height alone - height still feeds LaneDropRegistry, width feeds the replica - and BoardMetrics.cardReplicaWidth(measured:bodyPointSize:) keeps the old figure as the documented not-yet-laid-out fallback. Same row, same paddings, same lineLimit at the same width means the same height, so the preview is now an exact overlay of the face it left. Manual verification pending alongside the lane grab-point card: 3x vs 1x lanes, interior masonry columns, window re-divide, trash rows, large text sizes, drag-at-creation fallback. 3 tests. 1661 green on both schemes.
