/* =========================================================================
   ApexityEdu v3.0 — Premium design layer ("Aurora")
   =========================================================================
   A modern, sleek, high-contrast overhaul applied on top of the classic
   token system. Loaded LAST (after tokens/base/components/chrome/screens)
   so it can refine the SuperAdmin console, the admin/school app shell, the
   login experience and the PWA install page without rewriting them:

     • glassmorphism surfaces (translucent cards, blurred topbars/sidebars)
     • layered, softer shadows + gradient accent borders
     • micro-interactions (hover lift, press feedback, animated highlights)
     • high-contrast dark mode with elevated surfaces
     • polished KPI/stat cards, tenant switcher, filter toolbars
     • reduced-motion + mobile safe areas respected
   ========================================================================= */
