   gestures still need their own occurrence/order semantics and task verification.
 - Routing offers a usable initial path plus manual pins; arbitrary dense diagrams
   are not guaranteed crossing-free. Measured dense full solve119ms remains a limit.
-- R3 typed historical bodies plus finite proposals appear simpler than a separate
