   Si appoggia a style.css (variabili, header, footer, pulsanti, form) e a
   componenti.css (countdown, contatori, simulatore, FAQ, passi, CTA, nota
   legale, pulsante fisso, modalità presentazione).
   Qui restano solo l'accento caldo (ambra) e le parti esclusive della pagina.
   Animazioni: solo transform, opacity e stroke-dashoffset.
