Nithin2745/portfolio — reverse-engineered prompt

Build me a polished cosmic themed developer portfolio for Nithin Datta Attili in this repo. I want it to feel premium and futuristic, with an immersive 3D space background, moving particles, planets or orbital elements, smooth scrolling, and cinematic section transitions.

The site should introduce Nithin as a Flutter Developer, AWS Cloud Engineer, and Full Stack Developer, then show his skills as an interactive tech constellation where hovering over items reveals short details or stats. Add a custom sci fi cursor that shows tiny telemetry style text and changes context over links, like follow, connect, open, or mail.

Create a clean contact area with a balanced 2 by 2 grid for Email, LinkedIn, GitHub, and Instagram using these details from the README. Make it responsive, fast, and not cluttered on mobile. Use the existing React, Vite, TypeScript, Tailwind, Three.js, GSAP, and Framer Motion setup, and make sure npm run dev and npm run build work. Look up current docs online if you need to.
