/* ==========================================================================
   LOGIN / REGISTRAZIONE - Apple Style Premium v5 (Standalone Theme)
   ==========================================================================
   [v5.0.9] Riscrittura completa per il markup reale del tema:

   body.woocommerce-account
     └─ main#primary.site-main
          └─ div.container
               └─ div#content.site-content
                    └─ article
                         ├─ header.entry-header > h1.entry-title
                         └─ div.entry-content > #customer_login

   Nessun parent theme da sovrascrivere. Gli override sono solo su:
   - .container (core.css: max-width) → espanso a 100%
   - #primary (core.css: padding-top) → rimosso
   - WooCommerce .col2-set (woo default: 2 colonne float)
