   Style Skill 主题层
   ----------------------------------------------------------
   1) 亮色主题：按 Style Skill 令牌重构
        --color-bg      #F5F6F6
        --color-primary #F7F609
        --color-text    #1E1E21
      视觉手法：去掉照片背景与玻璃拟态，改成干净的浅灰画布；
      黄色只做强调（高亮块、标签、激活态、悬停），正文保持墨色；
      硬边偏移阴影只出现在可交互卡片/控件的 hover、focus 上。

   2) 暗色主题：只把强调色换成 #F7F609 的相反色（蓝色系），
      背景、文字、玻璃效果、版式全部保持原样。

   本文件在 custom.css 和各页面样式之后加载，用来覆盖主题默认值。
