/* Desktop responsiveness: the widget is designed phone-first (portrait,

   "device" instead of stretching full-width or staying tiny in a sea of
   whitespace. Canvas drawing is already fully proportional (drawRoad reads
   canvas.width/height each frame), so just scaling the CSS box is enough —
   no JS changes needed for the game to render correctly at the new size. */
