   牛来168 · 设计令牌层
   ------------------------------------------------------------
   色彩来源与架构评估：
   1) 本机已有 design_tokens.json（爱六π品牌色卡）：
      primary #E8A32E（橘金）、secondary #B8830F、highlight #FFF8EC
      —— 保留该主色基因，作为站点主色基准。
   2) 本机已有 Apple HIG 色彩参考：
      橘黄梯度 #FF9500 / #FFB340 / #FFD60A / #FFCC00 / #FFE45B
      灰阶      #F2F2F7 / #E5E5EA / #C7C7CC / #8E8E93 / #1C1C1E
      —— 采用其语义分层与灰阶秩序作为 Web 端基底。
   3) 综合结论：文档色卡偏"印刷/纸面"，Web 端需要
      更大的动态范围与更硬的层级对比。故在保留 #E8A32E
      家族的前提下，引入 HIG 灰阶 + HIG 橙梯度做亮度阶梯，
      并补充青色 #0A84FF 作为唯一辅助强调色（与 banner
      中青蓝能量带呼应），避免全站暖黄导致的视觉疲劳。

   z-index 只在定位元素上生效；calc() 运算符两侧留空格。
