   Chinese Stories · 自定义页头样式  (v3)
   报头（三栏：期号 / 文字报头 + 日期 / 账户 + 搜索）
   + 分类导航条（满宽平铺 + 吸顶）

   父主题 justnews 的页头 CSS 作用域是「body > header.header」，
   这里统一用「body > header.header.cs-header」前缀（多一个 class）：
     · 优先级高于父主题（多 1 个 class），无需 !important 硬抢；
     · 桌面端沿用父主题的吸顶（body.header-fixed）。

   报头 .cs-brand 与搜索面板 .cs-search-layer 在 <header> 之外，
   父主题没有针对它们的规则，命名全部走 cs- 前缀，互不干扰。

   断点与父主题对齐：
     ≥992px  = 桌面（三栏报头 + 满宽导航条 + 右侧搜索）
     ≤991px  = 移动（报头隐藏；矮条＝汉堡 + 品牌 + 搜索/账户；菜单原地展开）
   ========================================================= */

/* =========================================================
   0. 内容区宽度：1200 → 1320
   父主题用 :root{--theme-container-width} 分级控制 .container：
     ≥768px 750 / ≥992px 970 / ≥1240px 1200
   这里只覆盖 ≥1240px 那一档，并用 min() 防止窄屏溢出。
   末尾的 -60px 相当于左右各 30px 安全边距。

     · 侧栏无内容时隐藏它；
     · 主栏随之居中并限宽（列表页 880 / 文章页 720，正文约 680px ≈ 100 字符/行）。
