 * LA LISTA DE ESPERA DE Ü — dos partes y una sola protagonista.
 *  Parte 1 (marino): «Ü llega a tu computador» y el correo.
 *  Parte 2 (azul):   «Ya estás en la lista de espera. Pronto podrás descargar Ü.» Nada más: expectativa.
 *  El paso entre las dos es un círculo que se abre desde el botón; Ü no se va: celebra y se queda.
 *  Los azules del dueño (#13304f, #2f6eb5) y una sola cosa blanca: Ü.
