/* Auth pages: shared styles for /login, /signup, /forgot-password,

   Design language: card-based split layout — left visual panel
   (deep green, Serochat brand reinforcement) + right form panel
   (clean white, focused form). Sits centered on a muted paper
   background. On small screens the visual panel collapses and the
   form takes the full card.
