/* ===========================================================================
   Commodity FX Volatility Tracker — "Departures Board" design system
   Commodities tracked the way an airport tracks flights: a board that
   visibly reranks by volatility, changed rows lit and held, detail views
   read like a segmented boarding pass. Board surface + off-white flap
   characters + one reserved accent for chrome/alerts; gains/losses/
   informational data keep their own semantic hues (facts, not decoration).
