Bouncing Dots Overlay

# Integrate this UI component

Add this component to my project.

1. Install any missing dependencies.
2. Make sure Tailwind CSS is set up and scans the new file.
3. Prefer passing props over editing the component source — changing the component itself may break it.
4. Adjust colors, size, and layout via props or wrapper classes to match my project. You know my codebase better than this snippet does.

## Component source

```tsx
"use client";

import { useEffect } from "react";

type BouncingDotsOverlayProps = {
  open: boolean;
  onOpenChange?: (open: boolean) => void;
  label?: string;
  className?: string;
};

export default function BouncingDotsOverlay({
  open,
  onOpenChange,
  label = "Loading",
  className = "",
}: BouncingDotsOverlayProps) {
  useEffect(() => {
    if (!open) return;

    const overflow = document.body.style.overflow;
    const closeOnEscape = (event: KeyboardEvent) => {
      if (event.key === "Escape") onOpenChange?.(false);
    };

    document.body.style.overflow = "hidden";
    window.addEventListener("keydown", closeOnEscape);

    return () => {
      document.body.style.overflow = overflow;
      window.removeEventListener("keydown", closeOnEscape);
    };
  }, [onOpenChange, open]);

  if (!open) return null;

  return (
    <div
      role="status"
      aria-live="polite"
      className={[
        "fixed inset-0 z-50 grid place-items-center bg-slate-950/50 backdrop-blur-sm",
        className,
      ]
        .filter(Boolean)
        .join(" ")}
    >
      <div className="flex items-center gap-3" aria-hidden>
        <span className="h-3 w-3 animate-bounce rounded-full bg-white" />
        <span
          className="h-3 w-3 animate-bounce rounded-full bg-white"
          style={{ animationDelay: "150ms" }}
        />
        <span
          className="h-3 w-3 animate-bounce rounded-full bg-white"
          style={{ animationDelay: "300ms" }}
        />
      </div>
      <span className="sr-only">{label}</span>
    </div>
  );
}

```
