rasco100btw/Social_App ? reverse-engineered prompt

Build me a simple social app where people can sign up, log in, and see a feed of posts. I want users to be able to create a post, like or comment on posts, and view basic profile pages for other users.

Make it feel clean and modern, with a mobile friendly layout that also works well in a browser. Use the existing project setup, and wire it up so the app actually works end to end with the backend already included in the repo. If you need to check current docs for anything, go ahead and look them up online.

Please also make the app easy to run locally, handle loading and error states nicely, and add any missing screens or navigation needed so it feels like a real social app rather than a demo.
