 *    - File: page-narrazioni.php o template-parts/search-form.php
 * 
 * 2. IMMAGINI CARD (linee 742, 750, 758, etc.):
 *    - Attuale: alt="pt" (troppo generico)
 *    - Corretto: alt="Immagine percorso: [TITOLO]" o alt="" se decorativa
 *    - File: page-narrazioni.php (nel loop delle card)
 * 
 * 3. COOKIE BANNER (linea 212):
 *    - Plugin Complianz GDPR - aria-label="close-dialog"
 *    - Fuori dal controllo del tema, richiede aggiornamento plugin
 * 
 * 4. DIV CON ARIA-LABEL:
 *    - La maggior parte degli errori su <div> sono falsi positivi del validatore
 *    - I <div> non dovrebbero avere aria-label a meno che non siano interattivi
 * 
 * NOTA: Gli errori SC 2.5.3 sui <div> non interattivi possono essere ignorati.
 * Gli screen reader non annunciano aria-label su elementi non interattivi.
