/* ==========================================================================
   CLASS – Componenti condivisi
   Usati da index.html (home portale), serramenti.html e fotovoltaico.html.
   Si appoggiano a style.css.
   Il prefisso "pv-" delle classi è storico (nato nella pagina fotovoltaico) e
   viene mantenuto per non toccare quella pagina.
   L'accento di ogni pagina si imposta con le variabili --acc* sul <body>:
   fotovoltaico.css le porta all'ambra, serramenti.css al blu "vetro".
   Animazioni: solo transform, opacity e stroke-dashoffset.
