   心镜·解惑 对话版（P0）· chat.css
   ------------------------------------------------------------
   只服务新三页：首页 / 对话页 / 结论页。
   色板与字号严格照《极简首页视觉设计规范》+《对话页与结论页_界面规范 v1》：
     · 主色黛青 #2A5A6B（全页唯一强色块）
     · 文字三级 #1A1A1A / #4D4D4D / #8C8C8C；免责 #B3B3B3
     · 纯白底、标签底 #F5F7F8；留白 ≥70%；过渡 0.2s；无位移无放大
   与老站的关系：老站样式在 ui2.css / app.css，本文件不改它们、也不依赖它们。
