   CHINESE
   Not a translation layer — a second typographic system. Two things
   break when the same CSS carries 中文, and neither is the copy's
   fault: the display faces have no CJK glyphs, and every measure
   written in `ch` comes out half as wide as intended, because a Han
   character is roughly two `ch`. Both are fixed here rather than by
   making the English worse. Tracking tuned for Latin (.17em) reads
   as broken-apart on 汉字, and 9px is simply unreadable, so the
   mono chrome is re-stated too.
