The project is now TNCat, after HEIDENHAIN's TNC controls. Binary, QML module URI, settings path, bundle id and .desktop entry follow; the environment switches are TNCAT_*. Entertainment: a curled steel chip skitters in every minute or two, the cat runs it down and bats it away a few times before sitting back looking pleased. Mood changes flash the matching machine code above its head, G00 for a sprint, G01 for a stroll, M08 while it washes, G28 for a stretch, M30 for a nap. Window handling was split into two layouts. X11 and macOS keep one small window per object, positioned by the app. Wayland gets a screen-filling overlay whose input region is masked down to the cat, since a Wayland client cannot place its own window. Overlay mode is automatic there and available elsewhere via TNCAT_OVERLAY=1. Also adds a ground-line setting so the cat can walk above a softkey row.
