   AXIOM — Operating Surface Design System
   An instrument panel for decision systems, not a decorative skin.
   Calm, precise, dense, legible. Built for operators under pressure.

   Rules:
   • One signal accent (green) for live / positive / primary action.
   • Identity colors (navy/blue/red) never leak into general UI.
   • Red is negative data only — never buttons or headings.
   • Hairline grids. Left-aligned labels. Right-aligned numbers.
   • No gradients, shadows, glows, glass, icons, pure black/white.
   • Motion confirms; it does not entertain.
