tripal-pal/mern-task-manager ? reverse-engineered prompt

Build me a simple task manager app where I can add, edit, complete, and delete tasks from a clean web interface.

I want it to feel polished and easy to use, with a clear list of tasks, a way to mark things done, and some basic filtering or sorting if it makes sense. Please set it up as a full stack app with a frontend and backend, and make sure the data is saved properly instead of disappearing on refresh. If you need to, look up current docs online for the best way to wire everything together.

Keep the design modern but simple, and make it responsive so it works well on desktop and mobile. If there are any sensible extras like task details, due dates, or status labels, feel free to include them as long as the app stays lightweight and easy to understand. I’d also like the project to run cleanly with straightforward setup steps so I can start using it right away.
