/* --- Typography ---
   CJK-aware type scale.
   Chinese glyphs are denser than Latin — every size, line-height,
   and spacing value is tuned for mixed CJK + Latin readability.
   Key rules:
   1. No negative letter-spacing (breaks CJK square grid)
   2. Body line-height 1.8+ (CJK has no word-spacing, needs air)
   3. Heading line-height 1.2+ (1.1 causes CJK lines to collide)
   4. Min readable size 13px (CJK strokes blur below that)
