   della homepage (index-v2.html). NON tocca il sito attuale: index.html
   continua a usare style.css e non condivide una sola regola con questo file.

   Idea guida: il movimento racconta il mestiere. La rete dietro l'hero e' una
   rappresentazione del lavoro (pacchetti che viaggiano, minacce fermate al
   perimetro), il nome viene consegnato da quella rete, e ogni animazione di
   scorrimento e' legata alla POSIZIONE nella pagina, non a un timer.

   Tema unico scuro, dichiarato: ogni colore e' esplicito.
