/* BotVetrina — assistente fisso di Lumia GB su ogni pagina del sito.
   Stessa famiglia del widget «Provalo» (moduli/bot-prova/), pelle duo:
   nero #0C0C0B, arancio #FF6B1A la voce di chi scrive, verde #AFF23E
   la macchina. Nessun backend, nessuna dipendenza, gira offline.

     <script src="/moduli/bot-vetrina/bot-vetrina.js"></script>
     <script>BotVetrina.mount({ lang:'it', linkPrezzi:'prezzi.html' })</script>

   Risponde di prezzi, tempi e pagamenti; le richieste vere le gira
   a Lumia su WhatsApp. ?bv-auto=prezzi|tempi|parte apre ed esegue
   un flusso da solo (per screenshot e controlli). */
