Build me a fast browser based code playground where people can write code, run it safely, and share it with a link.

I want a clean editor experience with syntax highlighting, dark and light mode, and a polished modern look. Users should be able to sign up, log in, save their snippets, edit or delete them later, and open their profile to see what they’ve made. The main feature is secure code execution, so please run code in a locked down sandbox with sensible limits and no network access. Add rate limiting too so it is harder to abuse.

Please make the app feel snappy and simple to use, with the frontend and backend wired together so the whole thing works end to end. If you need to check anything current in the docs, go ahead and look it up online.
