/* --------------------------------------------------------------------------
   设计令牌 —— 全部取自线上 innei.in 的编译产物（而非仓库里停更的旧版）

     浅色：强调色 #c56473（深玫红）  根背景 #fefefb（暖白）  paper = 根背景
     深色：强调色 #e095a4（浅粉）    根背景 #1c1c1e           paper = neutral-2

   关键差异：中性色是**暖色系**（f9f8f5 → 141312），不是冷灰 zinc。
   旧版用的浅葱 #33a6b8 / Tailwind zinc 是错的，这是"不像"的主因之一。
