   Astra 子主题自定义样式总览
   ------------------------------------------------------------
   本文件为 Astra 子主题（astra-child）的额外 CSS，在父主题 Astra
   基础上做品牌化与体验微调，覆盖以下内容：

   1. 页眉：站点标题字体、下拉菜单外观（去箭头 / 居中 / 品牌蓝 hover）
   2. 文章页：隐藏作者日期、页眉分层、面包屑覆盖、灰底白卡片层次
   3. 自定义搜索结果页：两栏布局、筛选侧栏、结果列表、分页、响应式
   4. 移动端抽屉菜单：修复子菜单项文字被裁切

   说明：
   - 样式普遍以 !important 覆盖父主题 / Elementor 默认规则；
   - 品牌主色深蓝 #254195 用于 hover / 激活态；
   - 规则的实时生效依赖 WP Fastest Cache 的 CSS 合并功能处于关闭状态。

   注意：Astra 开启透明页眉（#masthead 绝对定位、层级 99、高度约 80–83px）
   时，面包屑作为 #primary 首个子元素会被压在页眉之下，需用 margin-top
   将其推到页眉下方（top ≥ 84px），避免上半截被页眉拦截点击。
