   WEIERXIN — 主样式
   --------------------------------------------------------------------------
   色值全部从 titan-vehicle.com 截图采样得出（不是目测）：
       #2489a7  主青蓝  页脚底色、链接、主按钮
       #085c74  深青    页脚底部条
       #ff9000  橙      行动按钮
       #272727  墨      标题
       #515151  灰      正文
       #e2e8f0  线      分隔线、卡片描边
       #f5f5f5  浅      次级区块底

   三条硬规矩（踩过的坑，别改回去）：
     1. 全局给 svg 定尺寸。图标若不写 width/height，某些浏览器按 300×150 渲染，
        整块布局会被撑破。
     2. 弹性子项要 min-width:0。flex 子项默认 min-width:auto，长单词（俄语、
        德语复合词）会把容器顶宽，手机右侧被裁掉而 scrollX 仍是 0，极难查。
        **不要**图省事写 `*{min-width:0}` —— 那会连带压扁图标和图片。
     3. 断点只有两个：1024px（桌面↔抽屉）、680px（双列↔单列）。导航抽屉用
        min-width:1025px，与 1024 成对，否则在正好 1024px 时两者同时消失。
