   Press Bench - bindery ticket skin.
   Cool press-grey paper, spruce ink, magenta stamps, perforated dotted rules,
   cut-corner cards, serif sentence-case display.
   Mobile-first: the base rules below are the 390px layout; every wider
   layout is added with min-width, in this order:
     390 (base)  ->  640  ->  768  ->  1024  ->  1200
   Budget held at 390x844: h1 <= 30px, section 1 <= 360px, no sideways scroll.
