/* ============================================
   DESIGN SYSTEM — Componentes ("Clinical Precision")
   ============================================
   Primitivos CSS puros. Usan los tokens de design-system.css
   (prefijo --ds-). Todas las clases usan el prefijo .ds- para
   convivir sin conflicto con las clases de producción existentes
   (.btn-primary, .modal, .toast, .badge, etc. en styles.css).

   Nada aquí se auto-aplica: una página adopta un componente
   agregando la clase .ds-* en su HTML cuando decida migrar.
