/*
  =====================================================================
  HAND RACING GAME — style.css
  =====================================================================
  Visual styling for the HUD overlay that sits on top of the 3D canvas.

  Key ideas:
    - The <canvas> is fullscreen (position: fixed, covers the viewport).
    - The #hud div is also fullscreen but has pointer-events: none so
      clicks pass through to the canvas.  Individual HUD children
      re-enable pointer-events where needed.
    - We use a dark, semi-transparent aesthetic with a neon-red accent
      (#ff3838) for a dramatic night-racing feel.
