/* ==========================================================================
   Quantum Capital — Quantum design system (PRD Section 46)

   The single stylesheet for every page. Mobile-first: base rules target a
   320px viewport; enhancements at 640/768px (tablet) and 1024px (desktop).

   Rules of the system
   - Colours come only from the §46 tokens or values derived from them.
   - Square geometry everywhere; only status badges are pill-shaped.
   - No gradients or drop shadows. Glow is reserved for the primary CTA and
     the equity / portfolio figure.
   - Surfaces are separated by 1px borders and hairline grids, not elevation.
