/**
 * Lever styles: an arcade cabinet arm that reads as part of the composer tool
 * row, plus the jackpot burst it fires when LiangShen mode lands.
 *
 * Semantic hooks are the data attributes (`data-dsh-plugin` / `data-dsh-part` /
 * `data-state`), never these hashed class names, so skins can target the lever
 * without a build-time dependency. Every animation is disabled under
 * `prefers-reduced-motion`, where the burst degrades to a short fade.
