   UnifiedSales OS — design system
   A revenue-operations console: layered slate surfaces, one indigo→violet
   brand gradient reserved for the spine (logo / active nav / primary
   action), disciplined status colors, mono-typeset data.
   Legacy token names (--bg, --panel, --card, --border, --blue, …) are kept
   so per-page inline styles continue to work.
