/* TrafficBay Product 002 - AI Visibility Spot Check (validation build).
   Mobile-first, self-contained (no third-party assets), premium-clean.
   Deliberately distinct from EXP001's PriceSheet Pro theme while following
   the same conventions: big touch targets, one primary CTA per screen,
   system font stack, no external dependencies.

   Motion rules: restrained 150-300ms transitions, one reveal animation on
   the report, nothing that delays or hides the workflow, and everything
   disabled under prefers-reduced-motion. */
