/* ==========================================================================
   Harley Street Classic theme
   Deep navy + warm brass/gold accent, serif display headings, calm and
   authoritative styling for an established private paediatric cardiology
   practice. Overrides Bootstrap 5's CSS custom properties so that existing
   Bootstrap utility classes (text-primary, bg-info, btn-outline-danger,
   card, alert-info, etc.) automatically pick up the new palette without
   any markup changes.
