/* ============================================================
   IRON CAPITAL MARKETS — Preloader
   ============================================================
   Matched to the IRON group loading screen used across the
   sister sites, so the family reads as one brand on entry.

   • The mark draws itself as a hairline, then fills.
   • A meter tracks REAL progress — readyState, images, fonts,
     window load — not a fixed fake timer, so it never shows
     100% while the page is still working and a warm cache
     lifts almost immediately.
   • Exit is a two-panel curtain that splits to reveal the page.
   • Muted brand red (#8b1a1a), consistent with the site.
