/* Layout: a risograph poster that runs and remixes itself (v4: every reload = a version the visitor hasn't seen, written by AI). Every load applies a remix: generated or curated ink palette
   (contrast-checked), display font, radius/border/tilt, hero layout, machine shape, section order, mosaic pattern and
   wording. Identity ("who's this") always follows the hero. Project facts are locked. Inks overprint (multiply / screen). */
