   fabric.css — strato "Global Fabric" sopra lo stile originale (27/09/2026)
   Struttura dal design system della dashboard lp365.site:
   Inter, etichette maiuscole spaziate, raggi 10px, vetro + cornice a
   gradiente, griglia di fondo, comparsa morbida.
   I COLORI restano quelli di Mare Conero (blu + semaforo), chiaro e scuro.
   Per tornare allo stile precedente basta togliere il <link> in index.html.
