   内容区淡彩卡片（参考「终极导航」的 12 色轮换）—— 仅浅色模式生效
   --------------------------------------------------------------------------
   参考站的做法是给卡片叠 12 个半透明色（如 #dcdffd8f / #c4fd3a3b），
   在白底上显出很淡的彩色。这里已按白底合成为「不透明」版本。
   参考站自己也是浅色页面上彩色、深色模式统一用深灰卡片，本站沿用同样思路：
   深色模式下淡彩规则完全不匹配，卡片保持原来的深色样式。

   使用方式：给内容块挂 .tint-1 ~ .tint-12（由 comm/foot.html 的脚本
   按 DOM 顺序自动轮换挂载），卡内文字/边框/按钮会自动转成深色系。
   不想被上色的块加 data-no-tint 即可跳过。
