   ULTIMI ARTICOLI — CAROSELLO ORIZZONTALE DI CARD LINKEDIN
   ========================================================================== */
/* Riga scorrevole di card, una per post incorporato da LinkedIn, in loop
   infinito (JS in index.html: liInitLoop/liScroll/liOnScrollEnd).
   Ogni card ha ALTEZZA fissa (--li-card-h, uguale per tutte) e LARGHEZZA
   proporzionale al post: l'aspect-ratio impostato inline sulla card (preso
   da width/height del codice embed di LinkedIn) determina la larghezza in
   base all'altezza fissa, quindi il post non viene mai ritagliato. Il
   contenitore .linkedin-wrap ha una larghezza massima calibrata per
   mostrarne circa 3 alla volta (dipende dalle proporzioni dei singoli post
   in carosello); i post più stretti o più larghi del solito mostrano
   naturalmente un po' più o un po' meno della terza card, com'è normale in
   un carosello con contenuti di larghezza variabile.
   Per un nuovo post: duplica un blocco .li-slide in index.html,
   incolla l'embed così come lo dà LinkedIn e imposta
   aspect-ratio: <width> / <height> con gli stessi numeri degli attributi
   width/height dell'iframe. */
