✨ Features

• Secure Authentication: Real JWT-based signup and login system utilizing bcryptjs.
• Dynamic Dashboard: Clean, card-based interface tracking overall link creation and real-time total clicks natively.
• Core Shortener Engine: Custom short-code generation routing directly to deeply nested destination URLs.
• Copy & Delete Workflows: Fully functional state-driven URL management.

🚀 Deployment

This system is strictly decoupled utilizing CI/CD pipelines to ensure maximum continuous uptime:

• Frontend: Deployed via Vercel with static .env injecting the production backend routes.
• Backend: Deployed via Render configured with dynamically guarded MONGO_URI and JWT_SECRET clusters.
