/* =====================================================================
   ThemeFix ADA — design system
   ---------------------------------------------------------------------
   This product sells accessibility, so its own UI is exemplary:
   - Teal accent on clean neutrals. No gradients, no Bootstrap look,
     no emoji icons.
   - Strong contrast everywhere; visible :focus-visible states.
   - Real semantic HTML (header/nav/main/footer) with a skip link.
   - Linear/Stripe-quality density for the dashboard: cards, compact
     tables, severity-ranked audit views.
