/* ---------------------------------------------------------------------------
   RC Info Solutions - shared login screen.

   Used by three sign-in pages that must read as one system:
       admin/index.cshtml         Admin Panel
       registration/index.cshtml  Candidate Portal
       department/index.cshtml    Department Portal

   Each page sets a role label; everything else is identical. Palette and
   geometry follow the brand banner - black and #eb1c24 on white, with
   diagonal slabs cutting across the panel.

   Load AFTER the theme CSS so these rules win.
