   修复补丁：浮窗目录点击失效（2026-08-19）
   根因：.toc-rail 带 transform（translateY/scale）会创建新的 containing block，
         使内部 .toc-rail-backdrop 的 position:fixed 相对浮窗而非视口，
         且 backdrop z-index(1000) 高于目录内容(默认 auto)，
         → 遮罩盖住整个目录列表，点击目录项实际命中遮罩 → 触发关闭而非定位。
   修复：去掉浮窗 transform（动画改用 opacity/visibility，遮罩恢复全屏），
         目录内容显式 z-index 提升到遮罩之上，保证可点击。
   交互：点"目录"按钮 → 浮窗弹出（全屏半透明遮罩 + 右下角浮窗）
         点目录项 → 平滑定位 + 高亮 + 自动关闭
         点遮罩 / ESC / 点目录项 → 关闭

/* ==========================================================================
   移动端主导航菜单可见性修复（cm-geek 主题，2026-08-19）
   --------------------------------------------------------------------------
   根因：
     原 .main-nav 在 @media (max-width: 860px) 硬编码 background: #0d1117
     （深黑），而 .main-nav a 的默认 color 是 #24292f（深灰近黑）。
     在浅色主题下，深色背景 + 深色文字对比度几乎为 0（~1.2:1，远低于
     WCAG 4.5:1 标准），菜单内容（首页/留言板/分类/归档等 7 项）
     完全看不清，用户以为"菜单没展开/没反应"。
   修复：
     1. 菜单背景从硬编码 #0d1117 改为跟随主题的 var(--bg-card)；
     2. 菜单文字改为跟随主题的 var(--text-bright)；
     3. hover/focus 增加主题强调色 + 浅背景反馈；
     4. 当前菜单项保持主题强调色；
     5. 汉堡按钮在菜单打开时（.open）变强调色，提供视觉反馈；
     6. 提升 z-index 防止被其他层遮挡，加滚动以防菜单项过多溢出。
   不影响：桌面端（>=861px）主导航保持原横向布局不变。
