   Two audiences, one visual language. The teacher gets dense tables that stay
   readable at 100 rows; the student gets a single uncluttered screen with the
   clock and the submit button always in view.

   Colours come from the theme tokens with literal fallbacks, so an active
   Academic theme flows through and the default theme is unchanged.
