/* ===== Newsletter consent group ===== */

    Para la casilla de consentimiento del newsletter utilizamos un contenedor flex llamado
    `.consent-group` para alinear horizontalmente el checkbox y su texto.  El `gap` crea
    separación entre el cuadro y la frase, y `flex-wrap` permite que el texto baje a
    la línea siguiente en pantallas pequeñas.  Además, se ajustan colores y márgenes.
