  /* ── NIENTE SCATTO ALLA PRIMA APERTURA ──
     Misurato: la prima apertura di ogni tendina perdeva un fotogramma, le
     successive no. È il browser che costruisce il livello su cui animare —
     con dentro l'ombra da quarantaquattro pixel — mentre l'animazione è già
     partita. Il codice avvisa un attimo prima, quando il puntatore arriva sul
     campo o il campo prende il fuoco, e a tendina chiusa lascia andare il
     livello: tenerne undici accesi costa memoria e non serve.
     contain dice al browser che quello che succede dentro l'elenco non può
     cambiare il resto della pagina: così non ricalcola nulla fuori. */
