/* ==========================================================================
   EXPERIENCE.CSS — Teacher Portal redesign layer
   ──────────────────────────────────────────────────────────────────────────
   Loaded AFTER style.css on every page. Pure overlay: it never removes
   behaviour, it re-skins the shell and adds micro-interaction primitives.
   The teacher identity is "indigo observatory": a deep-indigo night scene
   on the auth pages and sidebar, with a calm, cool-tinted light canvas for
   the high-repetition working surfaces.
     1. Extended design tokens
     2. Micro-interaction primitives (ripple, press)
     3. Auth experience  (immersive indigo scene + solid panel)
     4. App shell        (dark sidebar, light canvas)
     5. Dashboard        (welcome hero, stats, quick links, upcoming)
     6. Dynamic centre content polish
     7. Task pages       (body.eval-body.xp-task)
     8. Shared UX widgets (ux.js dialogs, toasts, empty states)
     9. Reduced motion
