/* Human 2030 — English edition typography overrides
   ─────────────────────────────────────────────
   The Chinese edition is typeset for CJK: a Chinese serif, wide leading
   (1.95) for dense hanzi, and wide tracking (.22em–.34em) on small caps
   labels so ideographs can breathe.

   Latin text needs the opposite: a tighter serif with a larger x-height,
   less leading, and much tighter tracking — .3em looks broken on a 10.5px
   uppercase English word.
