   ⑫ 桌面端横向滑动可用性修复（2026-09-21）
   问题（线上实测）：>768px 时 .swipe-hint 被 display:none；
        且 .swipe-wrapper 的滚动条被 scrollbar-width:none +
        ::-webkit-scrollbar{display:none} 一并隐藏；
        纯 CSS 实现下鼠标既拖不动、滚轮也不转横向
        → 桌面用户看到卡片被切断，却没有任何办法「左右滑动」。
   处置：① 桌面端恢复可见滚动条与「左右滑动」提示；
        ② 卡片由 70%~80% 百分比宽度改为定宽 320px，一屏可见 2–3 张；
        ③ 拖拽 / 滚轮 / 键盘交互由 shared.js 末尾补齐。
   ⚠️ 触摸端（≤768px）行为不变，仍是原生手势。
