/**
 * AIEC 统一头部 CSS（2026-09-23 整合 · v1）
 *
 * 单一来源 ── 所有页面（首页 / 文章 / 栏目 / 搜索 / 自定义 / 笔记本折叠）
 * 的 .site-header / .main-navigation / .main-nav / .sub-menu 样式全部来自此文件。
 *
 * 一致性（2026-09-23 修复）：
 *   - .main-title a 统一 22px（之前首页/文章/搜索 22px，栏目 20px）
 *   - .site-header 统一 padding 24px 0（wabi 页面）
 *   - .inside-header 统一 max-width 1240px（wabi 页面；非 wabi 页面走 GeneratePress 父主题）
 *
 * 加载顺序（在 functions.php 内）：
 *   generatepress-parent → generatepress-child → aiec-header → wabi-*（按需）
 *
 * 内容章节：
 *   A. 基础布局（所有页面通用，PC > 769px）
 *   B. Logo / 标题 / 描述基础（默认 90px / 1.4rem，子主题范围）
 *   C. 主导航 + 子菜单基础（默认紫色渐变，子菜单桥等）
 *   D. Wabi 7 类 body 顶栏（白纸 + 琥珀底线 + 72px logo）
 *   E. 769px+ 大屏：横排整齐（导航文字底边与 brand 容器底边对齐）
 *   F. 769–1239px 窄屏桌面：双行顶栏
 *
 * 兼容性：
 *   - 非 wabi 页面（自定义页 / 登录页 / 笔记本折叠 等）走 A/B/C 节
 *   - wabi 8 类 body 页面（home / single / category / archive / tax-* / search）
 *     同时应用 A/B/C + D 节，D 节特异性 + !important 覆盖默认样式

   G. body.error404 纸感化（2026-09-23 v1.3 新增）

   让「页面未找到」也继承 wabi 主题，与首页 / 栏目 / 文章页视觉一致：
     - body 底色 = 纸感米色（覆盖父主题 #f7f8f9）
     - 链接色 = 墨色（覆盖父主题 #1e73be 蓝链）
     - 文章卡 = 透明（让 body 米色透出，覆盖父主题 #ffffff 白卡）
     - 404 标题 h1.entry-title = 衬线墨色 2.2rem（与 .page-title / .entry-title 一致）
     - 搜索框 = 米色 + 琥珀按钮（覆盖父主题深灰按钮）
     - sidebar widget = wabi 卡片（依赖 aicc-sidebar-shared.css 由 inc-aiec-category-sidebar.php is_404 触发加载）

   父主题 inline CSS 在 error404 上覆盖（specificity ~0,0,1,0）的样式，全部用 !important 压制。
