/* ==========================================================================
   Orbinex AI — site styles
   A product of Softvision Corp.

   Palette is a slate-teal instrument ground rather than the usual SaaS white:
   the product's subject is control and audit, so the page reads like a panel.
   Semantic colours (ok / hold / refused) are the product's own vocabulary —
   they are content, not decoration, and they are separate from the accent.
