/* iBus API portal (api.ibusisrael.online/docs) — the iBus design system v4 «Линии» applied to developer docs.
   The transit diagram is the brand: a quiet light shell, colour only where it carries a meaning — live (green), timetable
   (cobalt), stale (amber), disruption (coral). The one bold element is the navigation drawn as a line with stations.
   Logical properties only (HE / AR mirror by `dir`), code is always LTR, motion answers actions and respects
   prefers-reduced-motion. Tokens = the app's src/ui/tokens.css values. */
