   Direction: a trading terminal at rest. Deep ink ground, a single
   signal-green that only ever means "up" and a red that only ever
   means "down", gold reserved strictly for the brand mark and primary
   action. The signature is the tape — a live market band that runs
   through the hero as an architectural element rather than a widget
   parked at the top.
