For grid-lanes (masonry) layouts, the grid overlay now shows gaps between items in the masonry axis direction. Previously, only the bounding lines of the masonry axis were drawn, with no gap visualization between items. The implementation collects all grid items and their bounding boxes, groups them by their grid axis track, sorts them by position in the masonry axis, and draws gap regions between consecutive items within each track.
