/* ==========================================================================
   Dispatch — Design System
   A product of Civil Digital. Follows the Civil Digital site conventions:
   token-driven, system font stack (no external fonts), accessible, fast.
   Brand: navy (--navy) + teal accent (--teal), on light mist neutrals.
   Tokens match the Dispatch app itself (see docs/adr/0002-design-tokens.md
   in the app repo), which carried BoatLog's brand across on purpose.
