/* 问见官网 · 样式表 v2.0（2026-10-27）
   四端统一 A 方案：首屏深绿满版 + 正文米白
   视觉规范：深绿 #284E2A / 亮绿 #3A6B3C / 金 #B8935A / 深金 #8A6A38 / 浅金 #DCC49B
             米白 #FBF9F4 / 浅米 #F5F1E6 / 墨 #1F1F1D / 灰 #6B6B62 / 线 #E6E0D2
   设计原则：内容直出可抓取，不依赖 JS 渲染

   对比度实测（写死在这里，改色前先看这行）：
   #1F1F1D on 米白 15.8:1 ｜ #6B6B62 on 米白 5.1:1 ｜ #3A6B3C on 米白 5.7:1
   #8A6A38 on 米白 4.9:1  ｜ #FBF9F4 on #284E2A 9.5:1 ｜ #DCC49B on #284E2A 5.6:1
   #B8935A on 米白仅 2.85:1 → 只作装饰与深底小字，禁作浅底正文
