/* ── CTA persistente ──────────────────────────────────────────
   Acompaña el scroll entre el hero y el formulario; desde el formulario
   hasta el final no vuelve (lo lleva initCtaFijo).

   Tiene el estilo de los demás botones de la web —esquinas rectas, borde
   de 1,5 px y el barrido de relleno al pasar por encima— con el menta de
   la casa, que es como van los CTA en la zona oscura, y todo este tramo es
   espacio profundo. Lo que lo hace llamativo sin estridencias es la señal:
   un píxel que transmite, con un pulso cada pocos segundos.

   En escritorio va abajo a la derecha; en móvil es una barra de lado a
   lado, siempre a la vista mientras el hero ha quedado atrás y el
   formulario no ha llegado —antes se apartaba al bajar y volvía al
   subir, y como la lectura normal es bajar, en la práctica no se veía. */
