   Nova Venturies — design system
   A company that captures, splits, and redirects light —
   so the recurring visual device is a spectrum: one beam,
   separated into violet -> blue -> cyan -> amber, and
   reassembled. Used once per page as a real diagram, and
   as a thin rule elsewhere. Everything around it stays quiet.
