   Composición: el cierre cálido de la página. Titular en dos frases a todo el
   ancho; debajo, a la izquierda el WhatsApp dominante (un botón grande, no una
   tarjeta) con el mensaje real ya escrito en una burbuja, y a la derecha la
   réplica del formulario CF7 en una hoja blanca. Más abajo la FAQ compacta
   (#preguntas): título fijo a la izquierda, seis <details> a la derecha.
   Distinto de #precios (Bento con tarjetas de color) y de #porque. Solo tokens.
