/* =============================================================================
   airtrunk.css: Blue Water Shipping · AirTrunk OSE portal
   BWS house design system (matches the Newmont Ghana portal): BWS navy brand,
   strategic blue accent, light default + dark toggle (html[data-theme="dark"]).
   All tokens are CSS variables so the theme flips with one attribute. Same class
   vocabulary as the sibling Newmont portal plus a few AirTrunk-specific
   components (ring / seg / tabs / toast / attn / thread): all token-driven.
