/* ============================================================
 * header-nav.css —— 公共头部补丁样式（从 include/header2.html、
 * include/header.html 的内联 <style> 外部化而来，内容零改动）
 * 基础样式（header、#nav、.customs-submenu、.country-panel 等）
 * 仍由 /css/style.css 提供，本文件需在其之后加载。
 * .old-header-nav：旧版头（include/header.html，销售经理/总监模板）
 * 专用作用域，仅微调二级菜单位置，保持原有视觉不变。
 * .header-nav2：新版头（include/header2.html）独有规则的作用域（海关数据
 * 动态面板相关），旧版头没有该面板结构，加作用域避免样式泄漏。
 * ============================================================ */
