/* Night Freight — design-system rebuild for self_travel-5 (Four Nights West).
   Full dark-mode industrial timetable-poster system: near-black surface
   throughout (not just the header), condensed all-caps display type,
   zero border-radius, thick rule-lines instead of soft cards/shadows,
   invert-on-hover instead of lift-on-hover. Deliberately the opposite
   register from a light "paper" travel-guide look — this reads as a
   printed rail schedule / poster, not a lifestyle blog. Rebuilt 2026-09-18
   as part of the design-SYSTEM uniqueness pass (see PROCESS.md 2026-09-18
   rule) — the prior version shared an identical body/header/footer/card/
   button CSS architecture with self_travel-6 once variable names were
   substituted; this version shares nothing but selector names with it. */
