/* ==========================================================================
   ADMITITALY — design plan
   Layout: a poster wall. Full-bleed colour-blocked sections (flag green,
   paper, ink, scarlet) stacked like posters pasted on a Milan wall. One giant
   expanded display line per block, a tight grid under it, stickers rotated on
   top, and marquee "tape" strips between posters. Hard offset shadows, 2px
   ink borders, almost no radius. Single deliberate theme: a poster has one.
