   Liste lunghe: il browser non disegna cio' che sta fuori dallo schermo.

   dalla vista. Il DOM e i link restano al loro posto, quindi i crawler e

   il lavoro del browser.
   L'unita' e' il GRUPPO di modelli, non la sezione: misurato nel browser,
   un gruppo e' 75 px (max 151) e una lista 44 px, mentre una sezione va da
   180 px (pagine modello) a 2.778 px (pagine /size/), e una sola stima non
   andrebbe bene per entrambe. `contain-intrinsic-size: auto N` da' al
