/* =========================================================================
   templateicl10 — B 骨架（双栏侧边栏式）
   参考谱系：原创。冷色系（午夜蓝 + 电光蓝 + 暖白），与 icl9 的撞色绿红完全区分。
   结构：sticky header → 深色 hero 带 → 双栏（正文主栏 + 粘性侧栏）→ footer
   约束：
     1) 所有类名带 cl10- 前缀，基础样式一律以 .cl10-body 限定作用域，
        避免 0-1-1 特异性跨皮肤污染（icl1 v3 起的强制规范）。
     2) 颜色/圆角/间距全部走 :root token，组件内不硬编码 hex。
     3) 正文 h2/h3 的边距一律用直接子选择器（.cl10-article > h2），
        否则 JS 运行时搬进卡片/手风琴的标题会继承正文间距，撑出大片空白
        （templateicl9 的 cl9-final 踩过这个坑）。
