   EduPlatter — design system v2 · "Open Campus"
   ----------------------------------------------------------------------------
   A light, wide, warm system for higher-education analytics. Paper and cream
   grounds, deep navy ink, one teal action colour. Colour is spent in two
   places: the soft mint marker that highlights the key word in a headline,
   and the gradient field behind the hero and closing panels.

   Type   Fraunces (display) · DM Sans (body) · DM Mono (labels, data)
