Keep one layout per output and virtual desktop. Move new windows to another existing desktop when the current page is full. When a user moves a window onto a full page, replace the last focused window on that page and send it back to the source desktop. Use stable slot swaps instead of insert splits so the layout shape does not change during moves.
