   PIXEL LP — pixel-art stylesheet

   TYPE SCALE — read this before changing any font-size.
   Zpix is a 12px bitmap font: its glyphs only land on the pixel
   grid at exact integer multiples of 12px. 13px/14px/16px scale
   the bitmap fractionally and go blurry; 9px/10px/11px crush the
   CJK glyphs into mush. So there are exactly three sizes here:
       --t-sm : 12px   (everything)
       --t-lg : 24px   (hero numbers, headings)
       --t-xl : 36px   (state art)
   Hierarchy comes from colour, spacing and surface — never size.
   Letter-spacing is whole pixels for the same reason.
