/* ==========================================================================
 * sections/crafts.css — 03 / 造物集：左侧手风琴 + 右侧固定展台
 * 依赖：tokens.css, base.css, components/section-header.css, components/tactile.css
 * 联动逻辑见 js/modules/crafts-stage.js
 *
 * 悬停态统一包在 @media (hover: hover) 里且保持原位 —— 媒体查询不改变层叠
 * 优先级，只按源码顺序参与，所以 .craft-card:hover 仍然排在 .craft-card.is-open
 * 之前，展开态照旧覆盖悬停态。
