/* M3.2.1 · Interaction Motion v15 ----------------------------------------
 * Motion language: restrained, physical, data-oriented.
 * - cards: 1~2px lift, never exaggerated
 * - buttons: hover lift + real press feedback
 * - live/online dots: slow low-amplitude breathing
 * - updated values: short "ink refresh", no bouncing counters
 * - sections: one-time soft reveal on entry / scroll
 * - charts: first appearance only; continuous telemetry redraw does not replay it
 * - reduced-motion: all non-essential motion disabled
