/* ============================================================================
   Tyre Route, Design System
   Implements tyreroute-design-reference.html: signal amber (the one action
   color), route blue (links/info/secondary), neutral ink on canvas/surface.
   Display = Space Grotesk, body = Inter, data = JetBrains Mono (all loaded via
   Google Fonts in the layout). Scoped to .th-root so it never bleeds into
   Metronic-styled pages elsewhere on the site.

   Legacy token names are kept to avoid a churn pass across ~1000 selectors:
   "--th-orange" now carries the signal amber (not red), and "--th-cream-2"
   carries the canvas grey. Substitute mentally when reading old rules.
