/* The CX Operator — design system.
   Precision dark "control room" publication: near-black console surfaces, hairline
   borders, squared radii, Space Grotesk display over an IBM Plex Mono metadata layer.
   Signal green (#22C55E) is a STATUS color — markers, live indicators, selection,
   primary action — never decoration. Motion is fast and crisp: 120–150ms hovers,
   400ms reveals, steps() for the cursor. One canonical file per brand. */

     used to sit on a near-identical neutral/warm near-black (#0C0A09) and the two
     sites were indistinguishable at a glance. Ventures has moved to salmon paper;
     operator stays the network's only dark site and takes a ground with an
