   NextClass · AUI — styles
   Concept: a departures board for classes. Dark board surfaces for
   what is live (hero, next up, headers), paper for what you work on.
   Type: Archivo (condensed for signage, normal for reading)
         + Martian Mono for tiles, times and codes.
   Motion: strong ease-out, UI under 300ms, press feedback everywhere.
