/* ═══════════════════════════════════════════════════════════════════════════
   assets/student/components/tutorial.css
   Portal-wide tutorial overlay.

   Injected into EVERY student surface — the dashboard and all twelve minisites,
   each of which ships its own unrelated stylesheet. So:

     · every selector is prefixed .stut- and nothing is styled by element alone;
     · every value the card depends on is declared on .stut-root rather than
       inherited, because a host page's `body { font-size: 18px }` or `* { }`
       reset would otherwise reach in here;
     · no web font is loaded — 'Outfit' is used if the host page already has it
       and a system stack takes over if not. One overlay is not worth a
       render-blocking font request on twelve minisites.

   Palette matches assets/student/dashboard.css (warm paper / terracotta), but
   re-declared locally so the overlay looks the same on a minisite that never
   loaded dashboard.css.
