   Kanvel: the hero and the one sentence (DECISIONS 192)

   The hero is the product's moment, played: asked, written, held at the gate
   until the visitor signs. hero.js runs the card and the particle field; with
   no script or with reduced motion the card is a still of the waiting proof.
   The sample is a specimen, so it waits in blue pencil (--info), like the
   console's tour; vermilion stays for a real person's real decision.
