   explorer.css — Estilos del Simulador de Explorador de Archivos
   Parte de: tasks/explorer_task/css/explorer.css
   
   NOTA DE DISEÑO:
   Este archivo tiene dos secciones bien diferenciadas:
   
   1. MENÚ DE SELECCIÓN — pendiente de migrar al Design System
      de Ayax Profesor (ver DESIGN_SYSTEM.md). Actualmente usa
      el estilo Windows genérico como el resto.
   
   2. SIMULADOR — mantiene intencionadamente la estética de
      Windows Explorer para que el alumnado reconozca el entorno
      real. No se aplica el Design System aquí.
