/* BMW M–style structure (see DESIGN.md) on a bright, high-contrast canvas by default.
   Type: Barlow, a grotesk modelled on highway and transit signage, chosen because this is a
   wayfinding tool (clear numerals, legible at a glance). Barlow Semi Condensed sets the
   uppercase labels and headings so long station names still fit. Every text colour below
   meets WCAG AA (4.5:1) against its background. */
