   CaratOS Marketing Theme — shared across all public marketing pages.

   Differentiation note: karatos.in (direct trademark-dispute competitor)
   uses cream+gold+serif in light mode and black+gold in dark mode. This
   theme deliberately avoids gold entirely — graphite/ink base, emerald
   accent (already the app's own "active/success" semantic color, see
   css/styles.css --emerald), bold geometric sans display type instead of
   a delicate serif, and floating real-product UI cards instead of
   abstract badges/line-art.
