{{--
    resources/views/customers/_form.blade.php — Partial del form cliente

    Il prefisso underscore (_form) è una convenzione per indicare "partial view":
    frammenti di HTML riutilizzati in più pagine tramite @include().

    Questa tecnica evita di duplicare il form identico in create.blade.php e edit.blade.php.

    La variabile $customer viene passata da edit.blade.php. In create.blade.php
    non esiste, quindi usiamo old() come fallback per ripopolare dopo errore.
