/* ======================================================================
   ZUGPULS · "Nachtzug" Edition · v3 (dark departure-board redesign,
   2026-06-10)
   ----------------------------------------------------------------------
   Ground-up visual redesign of the v2 layout. The DOM and all class/ID
   hooks are unchanged (app.js untouched apart from chart colors); only
   the design language is new:

   · Dark "Anzeigetafel" aesthetic: deep blue-black surfaces, the hero
     board sits on an even darker inset panel like a station display.
   · Brand kept (cyan #00B4F0, coral #FF4757) but used as light sources:
     glows on dots, focus rings, active states – not as fills everywhere.
   · Type system: Barlow Condensed (signage display), Inter (UI),
     Spline Sans Mono (times, delays, platforms, line chips).
   · Delay tones re-tuned for dark backgrounds (emerald/amber/orange/red).
   · Fernverkehr chips invert to light-on-dark (white chip), Nahverkehr
     stays cyan – same semantics as v2, higher contrast.
