   2026-09-22 第三轮：老邓要求 LOGO 整体再放大 30%。

   ⚠️ 改净高必须同时改的联动点（全站 4 处，漏一处就错位）：
      ① 本规则 .nav__inner height
      ② @860px 移动菜单 inset: 96px 0 auto 0
      ③ @860px 移动菜单 max-height: calc(100vh - 96px)
      ④ @520px .nav__inner height: 86px + .nav__menu inset: 86px
      ⑤ .pagehead padding-top（内页页头让位）
      main.js 用 nav.offsetHeight 动态取值，无需改。
   图形标：等比放大，保留橙绿双叶的辨识度。
   图标为纺锤形（上下皆尖端、最宽处约在 44% 高度），光学重心偏上，
   故用 translateY 做视觉对齐补偿，避免下端尖角显得下坠。 */
