What concrete timing and easing values do Material motion tokens give, and what does Apple's HIG say qualitatively about motion?
Material Components for Android defines 16 motion duration tokens from 50 ms to 1000 ms and seven easing curves (standard cubic-bezier(0.2, 0, 0, 1); emphasized-decelerate (0.05, 0.7, 0.1, 1)), and says duration should grow with how far the animation travels. The doc read doesn't mention reduced motion. Apple's HIG gives no numeric timings. It asks for brief, purposeful motion that is optional (not the only way to convey information) and warns against sustained oscillation around 0.2 Hz, which people are especially sensitive to.
