   v6 = design del sito dal 29/09/2026: la v4 «Sistema colibrì» con l'hero
   video della v3 (scelta della cliente). Carica DOPO v4.css, che resta la
   pelle di tutto il sito (<html data-variant="v4">). Qui solo:
   1. l'hero video, portato ai colori della v4 (viola pieno #513c90 invece
      del viola profondo della v3, angoli 0, occhiello col quadratino giallo);
   2. i componenti nuovi del Word del 29/09 nella pelle v4.
