   处理：把页面级容器上限提到 96rem / 1536px；水平内边距保持 px-4/6/8(32px) 不变。
        在 1728px 视口下内容左右边距约 128px（占 7.4%），与参考站 7.3% 基本一致。
   安全性：全站 406 处 max-w-7xl 全部落在 <main> / <div> / <section> 页面级容器上

   三个模块按顺序：
     .mx-hero    深色主推横幅（文案左 / 车右）
     .mx-detail  浅色细节三联（满版照片 + 编号 + 微文案）
     .mx-pair    昼 / 夜双车对照（左右各半，整块可点）
   设计原则：完全沿用 S600 横幅的设计令牌 —— 同一套色板（#0E1216 / #F4F6F7 /
   #C8FF3D）、同一款 Barlow Condensed 700、同样的直角与 hairline、同样的
   1536 + clamp(20,4vw,32) 栅格 —— 让两个产品章节读起来是一套语言，而不是
   两个拼贴。作用域全部收在 mx- 前缀内，不影响商城其它页面。
