   刘叔闲谈 样式表 — 现代新中式 · 轻国风浅色主题
   设计原则：清雅、温润、柔和、不刺眼，内容优先

   色彩系统（均已按 WCAG AA 校验对比度）：
     背景  浅米宣纸  #f5f0e6      卡片  月白  #fdfbf6
     主文字 墨灰      #333333      正文  炭灰 #595959
     强调  低饱和黛蓝 #4a6b85     辅助  赭石 #a0672d
     特殊状态 松绿    #3f7257      分隔/描边 #e7dfcf

   ★ 如何换主题：
   1. 改下方 :root 变量即可换配色 / 圆角 / 字体 / 间距；
   2. 全站中文统一使用「京华老宋体」（本地子集化 woff2）；
   3. 梅花暗纹 / 水纹分隔线为 data-uri SVG，可自由增删。
