   v12：顶部导航折行修复
   ------------------------------------------------------------
   问题：菜单增加到 10 项后，在 1025~1440px 这段宽度下每一项被 flex 压缩，
   中文在项内折成两行 ——「首页」变「首／页」、「关于我们」变「关于我／们」，
   整排导航看起来是坏的。
   v11 只做了「容器加宽 + 分级压缩间距」，缺了最关键的一条：禁止项内折行。

   做法：
   ① .nav a 永久 nowrap —— 这是根因，项内绝不折行；
   ② 按宽度分档收紧内边距与字号，保证 10 项在 1025px 以上都能单行排下；
   ③ 先隐藏冗余元素：头部电话在页脚、右侧悬浮按钮、各处 CTA 里都重复出现；
   ④ ≤1024px 交给原有的汉堡菜单，这里不管。
