Please implement this code in the current project and add it to (Your Desired Section, e.g. homepage hero, pricing page, dashboard). Change the primary accent color to (YOUR HEX CODE COLOR, e.g. #6366F1).

Requirements:

- Install dependencies if needed: npm install react react-dom
- Keep the layout responsive on mobile and desktop
- Replace placeholder copy with content that fits the project

The UI code:

const PARTICLES = Array.from({ length: 24 }, (_, i) => ({
  id: i,
  left: `${(i * 13 + 5) % 95}%`,
  size: 4 + (i % 4) * 2,
  delay: `${(i % 8) * 0.6}s`,
  duration: `${4 + (i % 5)}s`,
}));

export function FloatingParticlesBackground({ children }: { children?: React.ReactNode }) {
  return (
    <div className="relative min-h-screen overflow-hidden bg-gradient-to-b from-zinc-900 to-zinc-950">
      {PARTICLES.map((p) => (
        <span
          key={p.id}
          className="pointer-events-none absolute bottom-0 rounded-full bg-emerald-400/40 blur-[1px]"
          style={{
            left: p.left, width: p.size, height: p.size,
            animation: `float ${p.duration} ease-in-out ${p.delay} infinite`,
          }}
          aria-hidden
        />
      ))}
      <style>{`@keyframes float{0%,100%{transform:translateY(0);opacity:0}10%{opacity:.8}90%{opacity:.3}100%{transform:translateY(-100vh);opacity:0}}`}</style>
      {children && <div className="relative z-10">{children}</div>}
    </div>
  );
