Futuristic CRYSTAL Glass Button with codeXsg

✨ Liquid-glass look: a transparent crystal capsule with real thickness, a bright edge highlight, soft refraction, and a strong rainbow reflection on the floor beneath it.

🔮 Living details: a glass ball with a rainbow prism inside, and light arcs that circle it slowly and continuously.

💡 Click light and sound: pressing squashes the button like real glass, with a crisp click sound and light particles. A wide bulb-yellow light then loops around the border, and keeps looping while the button is loading.

⚙️ Production-ready: React + TypeScript with Framer Motion tilt and spring, light/dark/studio themes, three sizes, keyboard and screen-reader support, and reduced-motion support.
