   DUSKRUNNER V2 — style.css
   Premium dark-futuristic arcade UI: glassmorphism panels, neon accents,
   v1 heritage (green highway-sign HUD chips, amber chunky primary buttons,
   Big Shoulders Display headings). Fully responsive: desktop → phone
   portrait/landscape. Gameplay surfaces use touch-action:none; scrollable
   lists re-enable pan-y.
