/* =========================================================
 * BN-B2B-CN 前端样式表
 *
 * 原则：
 *  - 全部基于 CSS 自定义属性（与 theme.json 预设同源）；
 *  - 零框架、零外部字体引用（国内字体栈）；
 *  - 组件样式按 BEM 命名，避免与核心块样式冲突；
 *  - 响应式：桌面 4 列 → 平板 2 列 → 移动 1 列。
 *
 * 颜色变量映射 theme.json 预设：
 *   primary #0057A8 / primary-dark #003B6F / accent #00A3E0
 *   amber #FFB400 / graphite #2B3440 / slate #5B6770
 *   steel #E8EEF3 / white #FFFFFF / ink #10161C
