   - 用 right 而非 right:1px，避免压住卡片右边缘
   - 磁贴模式给卡片加右内边距，给按钮留出独立空间，

/* ============================================================
   隐藏滚动条
   ------------------------------------------------------------
   需求：各模块的滚动条太丑，统一隐藏。
   但**滚动能力必须保留** —— 只是不显示滚动条轨道，
   鼠标滚轮、触控板、触摸滑动、键盘方向键都照常可用。
   这也是 macOS 系统的默认行为（系统级「自动隐藏滚动条」）。

   实现要点：
   1. ::-webkit-scrollbar  —— Chrome / Edge / Safari（覆盖 width/height 即可隐藏）
   2. scrollbar-width: none —— Firefox 的标准属性
   3. 只写这两条，不要用 display:none 隐藏滚动容器本身，
      也不要用 overflow: hidden 改掉容器的滚动属性 ——
      那会真的失去滚动能力。

   放在文件末尾，确保能覆盖前面所有针对具体容器的滚动条样式。
