/* style.css — appmajic.ai marketing site design tokens + components
   Art direction: enterprise-grade local-AI infrastructure. Deep graphite/near-black
   surfaces, signal-violet primary + luminous teal secondary, quiet grid texture.
   Distinct from install.appmajic.ai's onboarding-wizard palette while remaining
   in the same brand family (shared violet/teal duotone, different type pairing
   and a heavier, more editorial hero treatment for a marketing/conversion page). */
