   OSOM SCHOOL — Design System
   Retro-desktop / Y2K-tech aesthetic, built from brand kit:
   Retropix (pixel) + Some Time Later (bubble) on a coral /
   navy / off-white palette. Signature element: the "OS
   window" card, lifted straight from the brand's own
   moodboard of CRT monitors and dialog boxes.
