   Di default il contenuto è SEMPRE visibile (opacity:1): funziona così
   anche senza JavaScript. Solo se lo script gira davvero, l'elemento
   riceve la classe .ph-pre (nascosto) PRIMA di essere osservato, e la
   perde nello stesso istante in cui riceve .is-visible — le due classi
   non coesistono mai, quindi non serve mai risolvere una parità di
   specificità tra loro (pattern robusto anche su motori datati). */
