/* portal.css - 化工门户共用块样式（BEM 命名，流式布局版）
 * 适配 _LayoutPortal.cshtml 嵌套布局：每个模块为全宽 flex 块，顺序堆叠。
 * 数值参照 shouye/index.css 原型，但改为流式定位（不用绝对 margin 偏移）。
 * 包含：.page 根容器、TopBar、HeaderLogo、Nav、Breadcrumb、FriendLink、PortalFooter
 */

/* ===== .page 根容器 =====
 * 设计稿基于 1920px，内部内容保留 1:1 像素坐标；
 * 容器使用 width: 100% + overflow: hidden 防止窄屏出现横向滚动条，
 * 内容超出右侧部分会被裁剪（1920px 以下视口可见主要区域）。
