   AURELIA COSMETICS v2.0 — 精装修升级层 (Upgrade Layer)
   --------------------------------------------------------------------------
   本文件在 style.css / i18n.css 之后加载，负责：
     1. 完整设计令牌补齐（间距 / 字号 / 圆角 / 阴影 / 语义色）
     2. 对比度与无障碍修复（AA 达标）
     3. 吸顶导航 + 滚动进度 + 巨型下拉菜单（MOQ 起订量）
     4. 商品卡图上层「加入购物车 / 立即购买」
     5. 图片放大镜（hover zoom lens）
     6. 详情页：主图居中、右上吸顶购买面板、抽屉、入场动画
     7. 信任体系（资质条 / 保障徽章 / 页脚联系方式）
     8. SPA 艺术底图容器与微交互

   约定：新增类名统一 ux- 前缀，避免与既有样式冲突。
