/* ==========================================================================
   Auth pages — login, signup, forgot password, reset password.

   Split-screen shell: photo on the left, form panel on the right, stacking to
   a banner + form on narrow screens. Shared by all four pages so they read as
   one flow; each page only supplies its own copy and fields.

   These pages no longer load Bootstrap, so the few Bootstrap classes the
   inline JS still toggles (.hide/.show, .alert-*, .text-*) are defined here.
   Keep them — authenticate_login.php responses drive them.

   Type stack matches nav_include_2.php (Inter, then system) so the admin and
   the door into it feel like the same product. No webfont request.
