   Archetipo H9: livelli in parallasse, tre telefoni disegnati in HTML e forme a profondità diverse.
   Firma: i livelli si muovono a velocità diverse con lo scorrere e con il mouse (desktop).
   Elementi di Marco (§3b): 3 numeri che contano, 4 titoli con il colore che scorre sulle lettere,
   5 sfocatura di movimento sulle foto che entrano, 8 nastro di carte infinito con bordi sfumati, 6 Lenis.
   Colore pieno: lilla, inchiostro e giallo. Raggi grandi (28px), bottoni a pillola. */
