   Scura come il resto del sito, possibile solo da quando le immagini sono

   forni multifunzione e le vetrine da terra sono neri lucidi: su un nero
   uniforme sparirebbero. Il gradiente radiale in alto fa da luce di studio e
   stacca i corpi scuri, l'ellisse chiara in basso (::before) è la pozza di luce
   su cui il prodotto appoggia — le immagini sono allineate tutte sulla stessa
   baseline, quindi la pozza cade sotto il prodotto in ogni card.

   Nessun padding sull'img: il margine di sicurezza è già cotto dentro la tela
