/* ============================================================
 * v1.2.1 修复：HTML 的 hidden 属性被组件 display 规则覆盖
 * .empty-state / .card / .row-between 等自带 display 的组件，
 * 优先级高于 UA 样式表的 [hidden]{display:none}，
 * 导致 JS 用 .attr('hidden',true) 隐藏元素时"隐藏无效"
 * （典型现象：购物车里明明有商品，空态提示却一直显示）。
 * 统一补齐高优先级规则，让 hidden 属性在任何组件上都真正生效。
