Prop	Type	Default	Description
`colors`	`string[]`	`chart-4, chart-1, chart-2`	CSS colors drawn from in order. Any CSS color or `var()`.
`speed`	`number`	`1`	Playback speed multiplier.

Also accepts all <div> props except children.

Decorative: the wrapper is aria-hidden and pointer-events-none, so it never takes focus or blocks clicks.
Under prefers-reduced-motion: reduce it draws one still frame and does not animate.

Each car is one depth value that accelerates as it nears; its trail is the line between where it was and where it is.
Fills its nearest positioned parent (absolute inset-0). Put page content above it with relative isolate on the parent and -z-10 on the backdrop.
Draws with the 2D canvas only (no WebGL, no extra packages), caps the pixel ratio, and stops its loop while off-screen or in a hidden tab.
