hisamuddin/dev-shelf ? reverse-engineered prompt

Build me a polished web app called DevShelf where people can discover, search, filter, save, and share useful developer resources.

I want a clean responsive frontend with pages for home, search results, resource details, categories, trending content, bookmarks, personal collections, contributor drafts and submissions, and an admin review area where items can be approved, published, or sent back with requested changes. Include simple demo sign up and login so I can test the full flow, and seed the app with realistic sample data so it works right away without setting up a database.

Make the backend a REST API with secure defaults, consistent JSON errors, a health check, request IDs, and a cache that supports TTL and invalidation. It should be runnable locally with one command, and also work in Docker. If you need to check current docs for any libraries or setup details, look them up online first.
