   Japanese rail wayfinding at night. The hub is a station; every destination
   is a colour-coded line. Three type roles: a signage grotesk (Zen Kaku
   Gothic New) for display, a pixel face (DotGothic16) for wayfinding
   furniture — eyebrows, badges, the departure board — and the system stack
   for body copy. Swap the tokens in :root to re-theme; nothing past this
   block should hardcode a colour.
