/* 1b. COMPATIBILITÀ LAYOUT BOOTSTRAP -----------------------------------------
   Scoperta di sistema: nessuna pagina carica il CSS di Bootstrap (solo il
   bundle JS, per i componenti Modal). Ogni schermata dell'app però usa da
   sempre la nomenclatura di classe di Bootstrap per il layout (d-flex, row/
   col-md-*, align-items-*, justify-content-*, form-check/form-switch...),
   dando per scontato che facesse qualcosa. Non ha MAI funzionato: gli header
   "flex" sono sempre stati normali blocchi impilati verticalmente, e le
   griglie a due colonne nei modal di modifica sono sempre state impilate a
   piena larghezza. Definiamo qui il sottoinsieme di Bootstrap 5 realmente
   usato nel markup, invece di caricare l'intero framework (rischio di
   conflitto con .table/.modal/.btn già personalizzati). */
