/* Login + OTP verification pages — a self-contained "brand" look distinct
   from the rest of the AdminLTE-styled app, since these are the one place
   an unauthenticated visitor lands. Navy/blue gradient matches the
   CheqExpress logo (icons/CheqExpress.png); kept as its own vars rather
   than reading assets/css/app.css's :root since these pages load this
   stylesheet standalone. See includes/otp.php::deliver_otp_email for the
   matching OTP email template colors. */
