   SHOP — 弹层清晰度修复（2026-09-20）
   ------------------------------------------------------------
   真正的根因有两条，都已修复：
   ① 遮罩盖在卡片上（最致命）：.shop-modal-backdrop 与 .shop-modal-card 是
      .shop-modal 的兄弟子元素。遮罩带 z-index（正向层叠组），卡片只有
      position: relative 没有 z-index（auto 层叠组）。按 CSS 绘制顺序，
      正向 z-index 组画在 auto 组之后 → **遮罩盖住了卡片**，弹层永远蒙着
      一层黑，遮罩越深越黑（这就是「一坨黑」）。见下方 .shop-modal 那组规则。
   ② 浮层被全站纹理层压住：body::before 是铺满视口的扫描线纹理，
      z-index: 9999，而浮层 z-index 只有 1500 上下。已统一抬到 102xx；
      站内其他浮层（作品灯箱 / 页头二维码 / 站内搜索 / 语言菜单）一并处理。
   ============================================================ */
.nav-toggle            { z-index: 10210; }   /* 仅在移动端媒体查询里生效 */
.lang-switch-menu      { z-index: 10220; }

   SHOP — 手机端两列紧凑网格（2026-09-24）
   ------------------------------------------------------------
   需求：手机上一屏至少能看见 4~6 件商品，淘宝式左右两列。
   做法（≤560px）：
     · 网格改 2 列；卡片瘦身——隐藏分类与描述、标题最多 2 行、
       适配信息压成 1 行省略号、价格字号缩小、内边距收紧；
     · 图片比例保持 4/3（比正方形矮），同样的屏高能多露半行；
     · 「加入购物车」变成圆形「+」（文字节点保留在 DOM 里，
       读屏与禁用态照常可读；缺货仍显示文字小标签，不误导）。
   ⚠️ 本块必须留在样式表最末尾：媒体查询不增加选择器特异性，
      放到前面会被上方同名基础规则覆盖。
