   Loaded by BOTH the standalone auth pages and the app shell.
   Keep this file limited to: tokens, base typography, .btn, .form-control,
   .alert, .badge and small utilities. It must NEVER style bare
   input/select/textarea elements (that lives in redesign-auth.css only),
   so nothing can leak into DataTables / select2 / topbar search in the app.
