/* ============================================================
   Ty i Ja (1960s Polish magazine) look, "pomegranate" palette.
   Four inks only, everything else a screened tint of these on
   the paper stock, as on a 4-colour press run:
     paper #F1E8D0   ink #131010
     pomegranate #9E2B3C (lead)   turquoise-green #31806E (accent)
     saffron #DBA02E (the <5% micro accent: stamps, threads)
   Flat throughout: no gradients, no blurred shadows. Offsets are
   solid ink, like misregistered print or stacked cut paper.
   This :root block is the SINGLE source of truth for every color
   on the page; app.js reads tokens via getComputedStyle.
