   R60 · teal 遗留清零
   --------------------------------------------------------------------------
   原来这里硬编码了一整套 teal 色值（原 --brand: #0f766e 等），依赖文件末尾
   的「令牌消费层」把它整体覆盖掉。这是脆弱设计：只要 tokens.css 未加载、
   或消费层被删除，整站立刻退回青绿。

   现在源头直接消费令牌，且 fallback 本身也是蓝色系 ——
   任何加载顺序、任何降级路径下都不会出现青绿。
   真正的取值定义见 assets/css/tokens.css。
