/* --- l'altezza dell'opening durante lo scroll ---------------------------
   Su iOS la toolbar di Safari si ritrae mentre si scorre, e `dvh` la segue:
   e' l'unita' dinamica, per definizione. `.v72-opening` e `.v72-opening-shell`
   la usano (v72_opening.css:91 e v72_04_opening.css:53/83, quest'ultimo dentro
   @media max-width: 780px, quindi e' quello che vince sul telefono).

   Conseguenza: mentre scorri, la sezione si allunga e tutto cio' che contiene
   slitta in giu' NEL DOCUMENTO mentre la pagina scorre in su. Il pannello
   video sembra allora inseguire lo scroll invece di uscire con la sua sezione.

   Simulato riducendo la toolbar di 55px, il collasso tipico di un SE in
   landscape: la sezione passa da 375 a 430, e la lane del video slitta da
   61 a 116 nel documento -- 55px esatti. Su un viewport alto 375 sono il 15%,
   ed e' per questo che si nota soprattutto li'; sui landscape piu' alti la
   stessa quantita' pesa meno e passa inosservata.

   `svh` e' l'altezza a toolbar ESTESA, cioe' la piu' piccola e l'unica
   stabile: la composizione entra intera al primo paint e non si muove piu'
   mentre si scorre. Quando la toolbar si ritrae si intravede la sezione
   successiva, che e' esattamente il comportamento voluto -- il pannello esce
   insieme alla propria sezione.

   Non e' un parallax: non c'e' nessuna trasformazione, solo un box che
   cambia altezza. Il fix non tocca position, transform o lifecycle.

   Solo la sezione: `.v72-opening .v72-opening-shell` alla riga 23 di questo
   stesso foglio e' gia' su `100svh` con specificita' (0,2,0), quindi la shell
   era gia' stabile e batteva il `dvh` di v72_04 da sempre. Questa regola non
   fa che estendere alla sezione la scelta che il foglio aveva gia' fatto per
   la shell.

   Stessa classificazione approvata altrove: capacita' + orientamento +
   altezza, mai larghezza. Questo foglio e' caricato dopo v72_04, quindi
   vince a parita' di specificita' senza bisogno di !important.
   --------------------------------------------------------------------- */

/* --- il portal in phone landscape ---------------------------------------
   Il blocco qui sopra esiste per annullare la composizione portrait di
   v72_16_opening.css, dove il portal e' un banner in alto: `top: 27.5%`,
   `left: 50%`, `border-radius: 0 0 30px 30px`, e la copy scende sotto con
   `padding-top: 35.8vh`. Li' azzera top, left, transform, border-radius,
   width e height -- ma non `max-height`, che quindi sopravvive.

   Quel clamp e' `max-height: 62svh !important` dentro `@media (max-width:
   699px)`: una soglia di sola larghezza, che percio' cattura anche un
   telefono in landscape stretto. A 667x375 vale 232.5px contro una lane
   alta 303.8: restavano 71.3px di lane nuda sotto il video, e il portal
   perdeva il rapporto della clip, che `object-fit: contain` incorniciava
   con 26.6px di barra per lato. Sui landscape sopra i 699 (844, 852, 932)
   il clamp non si applica e la composizione e' gia' corretta.

   In portrait il clamp serve ancora: misurato a 320x568 morde davvero,
   lane 362.3 contro portal 346.5, e tiene lo spazio per la copy. Non si
   puo' quindi togliere globalmente -- il blocco gemello dello stage porta
   `max-height: none !important` perche' li' non c'e' quel vincolo.

   L'override e' percio' circoscritto, con la classificazione gia' approvata
   altrove: capacita' piu' orientamento piu' altezza, mai larghezza, cosi'
   un telefono lungo in orizzontale resta telefono e nessun tablet entra.
   Sopra i 699 e' un no-op esatto, perche' li' non c'e' nulla da annullare.
