   QUAIVOX — DESIGN SYSTEM
   Signature idea: the "route line" — a thin signal path with a
   travelling pulse, standing in for the thing Quaivox actually
   does (routing calls, sessions and data reliably between
   platforms). It threads through the hero and reappears as a
   section divider instead of a decorative rule.
