/**
 * 动效配置（对应 #99 动效系统）
 *
 * JS 侧 duration（秒）与 CSS token（毫秒）映射关系：
 *   instant  0.12s ≈ --motion-dur-fast   (150ms)
 *   state    0.20s ≈ --motion-dur-fast   (150ms)
 *   panel    0.32s ≈ --motion-dur-base   (250ms)
 *
 * easing 与 CSS token 映射：
 *   enter  [0.2, 0.85, 0.18, 1] ≈ --motion-ease-out
 *   exit   [0.4, 0, 1, 1]       ≈ --motion-ease-in
 *
 * prefers-reduced-motion 由组件层 useReducedMotion() 控制，
 * CSS 层由 --motion-scale 联动（L0=1 / L1=0.3 / L2=0）。
