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

export default function SpinnerOverlay({
  open,
  onOpenChange,
  label = "Loading",
  className = "",
}: SpinnerOverlayProps) {
  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="h-12 w-12 animate-spin rounded-full border-4 border-white/30 border-t-white" />
      <span className="sr-only">{label}</span>
    </div>
  );
}

```
