/* ============================================================
   v23 · 文档语言（wiki）
   ------------------------------------------------------------
   来源：sample.html（财务分析报告）的排版系统，按 MSP 改造后接入。
   抄进来的：灰底白纸、报头粗线、h2 下划线分隔、KPI 三段式、
             语义状态色对、tabular-nums、口径声明块、严重度色块、
             打印分页控制。
   没抄的：  0 圆角铺满全站（会和外壳的圆角语言打架）、14px 正文、
             Arial 字体栈、amber 当警示色、钢蓝替换品牌蓝。

   作用域：视觉语言全部挂在 .doc 下（body.doc，只有 29 个 wiki 页带这个类），
           非 wiki 页面零影响。少数"缺陷修复"没有加作用域，见各处注释。
