/* ==========================================================================
   TrackLink — Design System
   A product of Civil Digital. Tokens are taken VERBATIM from the real
   TrackLink product — app/src/.../ui/theme/Color.kt (Compose) and
   web/src/theme.css (React Hub dashboard, confirmed byte-identical to the
   CSS served live at https://tracklink-a9030.web.app). Do not "improve" or
   approximate these — if a token doesn't exist in the product, don't invent
   a new brand colour, reuse the closest existing token instead.

   Structure deliberately mirrors the real app/web Hub's own design
   language, NOT the Dispatch/BoatLog navy-hero template: TrackLink is
   light-first with no dark scheme (Theme.kt: "there is intentionally no
   dark scheme; the brand is the light blue/white look with orange CTAs").
   The ONE dark accent anywhere in the real product is the footer band
   (web theme.css: "the light theme's single dark accent, coordinated with
   the marketing site") — so this site uses light sections throughout and
   reserves navy for the footer only, exactly like the app does.
