   CONA — Design System
   Corporativo Oncológico Nacional / Apps

   Fuente única de estilos para todos los sistemas de la plataforma
   (Almacén, RH, Compras, Portal, etc.). Se sirve desde
   assets.cona.com.mx/css/cona-design-system.css y cada módulo lo
   importa con un parámetro de versión (?v=<timestamp>) para evitar
   problemas de caché al actualizar.

   Origen: extraído y consolidado del SGA Pharma (primer sistema de
   la plataforma), ya validado en producción. No se cambia ningún
   color existente — solo se documentan y se agregan los tonos
   semánticos y componentes que los módulos nuevos van a necesitar.
