   Concept grafico: «la linea del tetto» (la diagonale di falda come motivo)
   Concept del movimento: «l'impianto si accende» — la pagina si alimenta
   mentre scorri: barra di carica, numeri che salgono, passi che si illuminano.
   Colori campionati dai pixel reali del logo del cliente.
   Regola ferma: se un effetto fa scattare lo scroll, l'effetto si toglie.
