/* ⚠️ ADVERTENCIA CRÍTICA:
   
   NUNCA uses valores rgba() hardcodeados directamente en tu CSS.
   
   ❌ MAL:  background: rgba(255, 255, 255, 0.5);
   ✅ BIEN: background: var(--gradient-secondary);
   
   ❌ MAL:  box-shadow: inset 0 1px 0 rgba(255, 255, 255, 0.5);
   ✅ BIEN: box-shadow: var(--inset-highlight-normal);
   
   Usar colores hardcodeados rompe el sistema de temas y causa
   que el modo oscuro se vea claro al hacer focus/hover en elementos.
   
   SIEMPRE usa las variables CSS definidas en este archivo para
   asegurar que los colores se adapten correctamente al tema activo.
