Motion
Every named curve and duration tier as something you can trigger, with a speed control. Motion values live in the afentakis-motion skill rather than in this repo's tokens, because a duration table copied into two files gets edited in only one of them.

The gallery of triggerable curves and durations lands once the pipeline has real components to demonstrate motion on. The chrome you are reading already runs on those values: the press, the hover, and the focus transitions here take the library curve and the press duration tier, and every one of them shortens under a reduced-motion preference.
