/* ============================================================
   IRON CAPITAL MARKETS — Premium Preloader
   ============================================================
   Strategy:
   • Full-screen dark overlay (#0a0a0a) with the logo centred.
   • Two concentric rings counter-rotate around the logo,
     one in brand-red (#C41E24) and one in a translucent white.
   • A thin progress bar sweeps across the very bottom.
   • On page-load the overlay slides up and out of view.
