   identity-theme.css — Unified styling for Area Identity pages
   Inherits color palette from sidebar.css for consistency

   Questo file fornisce uno STILE UNICO per tutte le pagine di 
   autenticazione (Login, Register, Password Reset, etc.) 
   mantenendo coerenza con la palette di colori del sidebar.

   PUNTO UNICO DI MODIFICA: Se cambi i colori qui, cambiano
   automaticamente in tutte le pagine Identity.
