   Panels — design system (students, teachers, school admins, providers, admin)

   An app-like shell in the spirit of Sanjaghak: dark by default with a soft
   aurora glow, a light theme, a floating glass tab bar on phones and a
   floating rail on desktop, big gradient hero cards, bento grids and
   bottom sheets. The classroom itself keeps app.css.
