💡 What is a UUID? A 128-bit identifier that is unique across space and time. Used for database keys, session tokens, distributed systems, and more.

🔒 Generated locally — all UUIDs are created in your browser using window.crypto.randomUUID() or custom implementations. Nothing is sent to any server.
