Class: CanvasRectSystem

A Canvas's own UI rect IS its design resolution, centred: the rect its children anchor to and lay out in has to be the one cameras fit to the screen, or layouts drift from what's shown. Kept here rather than trusted to whoever edits either value. Runs before Widget / Layout so they see this frame's rect; writes only on a mismatch, so dirty bits stay quiet.
