   SLOT IN CIMA COLLASSATO — da rimuovere il giorno dell'approvazione AdSense

   Finche' il sito non e' approvato Google risponde data-ad-status="unfilled":
   nessun annuncio viene servito, ma lo script AdSense scrive comunque
   style="height:280px" direttamente sull'<ins> (desktop; 390px su mobile),
   perche' lo slot e' data-ad-format="auto" + data-full-width-responsive="true".
   Il min-height:90px qui sopra non c'entra: perde contro l'altezza inline
   scritta dallo script sul figlio.
   Risultato: 280px di vuoto sopra la piega su 61 pagine, a fronte di zero
   ricavi, con il primo campo dei calcolatori spinto sotto la piega.

   Lo slot viene azzerato in altezza, NON nascosto con display:none: con
   display:none lo script AdSense va in eccezione su ogni pagina (verificato,
   0 errori JS prima e 1 dopo). Cosi' l'elemento resta misurabile e in flusso,
   ma non occupa spazio.

   PER RIATTIVARE: cancellare le due regole qui sotto. Il markup degli slot
   nelle 61 pagine non e' stato toccato.
