/* ==========================================================================
   South Wales Alloys — shared design system (site.css)
   Single source of truth for tokens + shared components.
   Page-specific CSS should only contain layout unique to that page.

   Brand direction (Phase 2): Inter (UI/body) + Bebas Neue (display).
   Unified red #C42020, gunmetal accent #3A3F44 (replaces the old orange-gold).
   Legacy variable + class names are kept as aliases so pages that have not
   yet had their inline CSS stripped continue to render correctly.
