/* ============================================================
   IRON MUSCLE GYM — Login theme
   Dark, athletic, energetic. Bootstrap 5 compatible.

   RESPONSIVE CONVENTIONS (keep these for all new design work):
   - Layout breakpoint: 992px (Bootstrap lg) — below it the brand
     panel hides and the form is centered full-width.
   - Never use fixed pixel widths on layout blocks; use max-width
     (e.g. .form-card max-width: 430px) so blocks shrink fluidly.
   - Fluid type via clamp() (e.g. .brand-hero h1).
   - Verify no horizontal overflow at 320 / 375 / 768 / 1024px.
