   Why: --serif named Songti SC, which ships on macOS and nowhere else. On
   Windows the whole stack missed and Chinese headings fell through to the
   generic serif — SimSun, a bitmap-era face that frays at display sizes — and
   most of the people who read the site in 中文 are on Windows. Worse, the Latin
   inside those headings came from Iowan Old Style, a warm humanist serif
   sitting directly against a rigid Ming face: two traditions on one line, with
   different stroke weights and different optical sizes. Noto Serif SC draws
   both scripts as one family, so a line like "Irwindale 工厂" finally matches
   itself. Loaded only where it is named — under html[lang^="zh"] — so English
   and Spanish visitors never fetch it. */
