Build me a simple social media app where people can sign up, log in, make posts, see a feed, and interact with other users. I want it to feel clean and modern, with the usual things someone would expect from a basic social app like profiles, posting, liking, and commenting.

Use the existing JavaScript project setup and keep the app organized in a way that makes sense for a social platform. If anything depends on current libraries or patterns, look up the latest docs online if you need to. Make sure the app runs smoothly, the main screens work end to end, and the data flow is wired up properly so users can create content and view it again later.

If you need to make reasonable assumptions, keep them simple and practical. Focus on getting a working social app experience first, then polish the UI so it looks good and is easy to use.
