The last three keyboard-only games are now click-to-play, so every game
in the package responds to the mouse.
Crazy Eights and President route their hands through the shared
cg-regions click map (President maps each rank group to a click); the
patience boards (Golf, TriPeaks, Pyramid) follow the solitaire keystone,
mapping exposed slots plus the waste and stock to their spots. Each adds
a card-size slider, [mouse-1], and +/-/0 zoom.
Add cgt-mouse-regions asserting the SVG click maps build (suite -> 116).
