shivahar-git/task-management-mern ? reverse-engineered prompt

Build me a simple task management app where people can sign in, create tasks, edit them, mark them done, and delete them when they are finished.

I want a clean web app with a nice front end and a back end that saves everything so the tasks are still there after refresh. Make it feel easy to use, with a dashboard style home screen, a task list, and a form for adding or updating tasks. It should be obvious which tasks are pending and which ones are complete.

Please set it up as a full MERN project, with the frontend and backend working together properly. Use sensible defaults, include any needed API routes and database models, and make sure the app runs smoothly from a fresh install. If you need to check current docs for anything, go ahead and look them up online.
