A cream-colored circle travels horizontally across a dark gray road-like band at the bottom of a page, looping back to the left edge when it reaches the right side of the viewport. The animation uses `requestAnimationFrame` to update the object’s `left` CSS property each frame. A CSS `transition` on `transform` provides a subtle hover effect that scales the circle and changes its color to wheat. The page background is defined with a CSS `linear-gradient` that separates the pale sky from the darker ground.
