/* AXS Performance Medicine, sito v2: "laboratorio notturno".
   Direzione: fondo nero cinematico, segnali fisiologici animati, tipografia condensata enorme,
   oro usato solo come segnale. Bande "paper" chiare solo dove serve leggere a lungo.
   Look unico (dark-first, non segue il tema di sistema). Angoli vivi, niente ombre, niente gradienti. */
