   CJK typography
   --------------------------------------------------------------------------
   Chinese and Japanese display type needs a smaller size, looser leading and
   no negative tracking — the Latin defaults crowd the characters. Synthetic
   obliques also look wrong on CJK glyphs, so emphasis falls back to the gold
   accent and weight instead.
