/* ---------- Chinese-language typography override ----------
   Chinese typographic convention is the opposite of English. Where English
   law firms use serif (宋体) for authority, professional Chinese-language
   sites use sans-serif (黑体). At screen sizes, Chinese serif has thin
   horizontal strokes that look skinny and stretched. The industry standard
   for Chinese-language legal/corporate sites (King & Wood Mallesons, JunHe,
   Yingke, Haiwen, etc.) is sans-serif throughout, with weight variation
   for hierarchy rather than family variation.

   Stack: Noto Sans SC (Google web font, primary) → Source Han Sans SC
   (Adobe, same metrics, common on macOS/Linux) → PingFang SC (macOS system)
   → Microsoft YaHei (Windows system) → Hiragino Sans GB (older macOS) →
   generic sans.
