   H2O Admin — Authentication screen
   --------------------------------------------------------------------------
   Self-contained: the login view does NOT use AdminLTE's .login-page /
   .login-box classes, so nothing here fights adminlte.min.css and nothing
   here can leak into the rest of the application.

   Layout: one centred card, split into a brand panel (left) and the sign-in
   form (right). Below 860px the card stacks and the brand panel collapses
   into a compact band above the form.
