/* Sistema visual · Aprendizaje
   Capa final sobre style.css. Dirección: plataforma académica con práctica guiada
   (referencia: Codecademy/Gamut). Reglas del sistema:
   - Tipografía con carácter: IBM Plex Sans para leer, IBM Plex Mono para datos,
     etiquetas y código (autoalojadas, OFL).
   - Paleta de marca con significado: azul marino = texto y superficies de trabajo,
     violeta = acción, amarillo = la acción siguiente sobre fondo oscuro y el foco,
     verde = completado. Sin degradados decorativos.
   - Bordes definidos y esquinas pequeñas (2 px controles, 4 px módulos). Sin sombras
     difusas: la profundidad aparece al interactuar, con una sombra sólida desplazada.
   - Una acción principal por vista; el resto son enlaces. */
