Subtle & sparing — motion clarifies a state change, it never decorates. Entrance: fade-up + stagger (320ms, 50ms steps) on first paint. Hover: 150ms colour/bg only. Drawer / Sheet: 250–350ms on ease-drawer. Toast: ~220ms in. Never: infinite decorative loops, bounce / overshoot, parallax, motion on hero type beyond a single fade. One accent motion per view, max. Always honour prefers-reduced-motion.
