/* ============================================================
   PRINTVENDO — PAPER ROUND
   The app's own ink system, lifted from printvendo-web/styles/tokens.css.
   Inverted photocopy: riso spot inks on toner black.

   Single visual world by decision — a zine is printed once, so there is no
   light mode and every colour is painted explicitly.

   Built for a phone held in one hand in a corridor: 48px touch targets,
   nothing that needs a second tap to confirm except the things that change
   a number.
