/* =============================================================================
   auth.css — pattern condiviso pagine pubbliche di autenticazione
   (Login, ImpostaPassword, PasswordDimenticata, AccessoNegato)

   Usato da BackOffice (Blazor Server, cookie auth con <form method="post">) e
   Mobile (Blazor WASM, EditForm + IApiClient). La struttura HTML e' speculare,
   la logica auth e' diversa. Pattern P5.5: sfondo neutro, card centrata con
   striscia brand 4px in alto.

   Sizing input/button: min-height 44/48 px per essere touch-friendly anche
   sul back office, senza media query — il pattern P5.5 era nato desktop-only
   con altezze ~36px, ora uniformato.
