 * CREA NETWORK — estilos compartidos (M5-A)

 * Prefijo exclusivo .cn- (CREA Network). Se apoya en los tokens --crea-* de
 * crea-design-system.css, que debe cargarse ANTES. Identidad: azul oscuro /
 * blanco / amarillo; el morado no es protagonista.
 *
 * Incluye lo común a la página madre y a las tres líneas: layout, header,
 * botones, primitivas de formulario, avisos (error / informativo), éxito y
 * footer. Los estilos propios de cada página viven en la propia página.
 * Mobile-first; breakpoints de referencia: 640 / 900 px.
