/* Revisionando — pagina per telefono e PC.
   Impianto: barra in alto + contenuto in colonna (max ~44rem) + schede in basso su telefono,
   barra laterale sopra i 900px. Tavolozza pastello (verde acqua, menta, pesca, lilla, cielo; niente
   blu MIMIT); tema scuro ardesia, non nero. Contrasti verificati AA. Il tema segue il telefono
   (o claude.ai, `data-theme`) salvo scelta in «Testo e colori» (`data-tema` = chiaro | scuro).
   `--scala` ingrandisce il testo (A−/A+); barra e schede crescono al massimo fino al 112,5%. */
