/* ZCOOL KuaiLe is Simplified, Huninn (jf-OpenHuninn 粉圆) is Traditional; each leads
   for its own script and backs up the other so a glyph one face lacks (e.g. the 简
   switcher label, absent from Huninn) still renders in a rounded CJK font rather than
   a mismatched system serif. Both are self-hosted (see fonts.css). */
/* Both CJK display faces ship a single weight (400). Headings ask for 600/700,
   so the browser would synthesize bold — doubling strokes on an already-heavy
   rounded face. Disable synthesis so CJK renders at its true weight; Latin runs
   (Fredoka, a real 300–700 variable font) keep their genuine bold. */
