/* ---------- Tessere: tagliano senza diventare contenitori che scorrono (audit mobile) ----------
   La luce che segue il puntatore (.bt::before, 360×360) sporge dalla tessera: con
   overflow hidden la tessera diventava un contenitore scorrevole via script, e il fuoco su
   «Apri la galleria» (tastiera, lettori di schermo) poteva far scorrere il suo contenuto,
   che sembrava tagliato. overflow: clip taglia allo stesso modo ma non scorre mai. */
