Fix: attempt for clipping bug - not fixed yet

 10. Scale-path physical positioning used non-integer coordinates in `setPosition`, triggering
     runtime arg errors (`expected i32`) and bypassing window fit updates.
+11. Monitor-fit cap remained too optimistic for large frame packs, so max scale could still exceed
