/* ==========================================================================
   墨云阁 · 布局排版优化层  (ink-layout.css)
   作用：在不修改 style.css / ink.css / responsive.css 的前提下，覆盖排版细节
   加载：header.php 的最后一条 <link>（位于 ink-auth.css 之后）
   原则：
     1) 只使用 CSS 变量与相对单位，暗色（[data-theme="dark"]）自动适配
     2) 全部为覆盖规则，删除本文件即可完全还原
     3) 只作用于博客正文相关页面，不影响视频/音乐/解析等独立页面
