   --------------------------------------------------------------------------
   Libreria di componenti del sito. Regole:
   - ogni valore di colore, font, raggio viene dalle variabili di btm-theme.css
   - ogni classe ha il prefisso "btm-" per non scontrarsi con Volia/Bootstrap
   - l'HTML dei moduli nel DB usa solo queste classi, mai style="" per
     colori o font: così al cambio tema segue automaticamente
   Caricato DOPO style.css e responsive.css.
