/* ================================================================
   ViewRelay — Portal Theme
   ================================================================
   Design system CSS para el portal de licencias ViewRelay.
   Basado en el mockup aprobado (Abril 2026).

   Referencia visual: Linear, Stripe Dashboard, Vercel
   Tipografía: Inter (sans), JetBrains Mono (mono)
   Grid: 8pt, 12 columnas responsive
   Escala tipográfica: Major Third (1.250)
   Accesibilidad: WCAG 2.2 AA

   Uso:
     1. Importar este archivo como base del portal
     2. Los componentes referencian tokens semánticos (--vr-*)
     3. Nunca usar valores crudos (hex) directamente en componentes
