shikha033/TaskMaster ? reverse-engineered prompt

Build me a full stack task manager called TaskMaster where people can sign up, log in, and keep track of everything they need to do in one place.

I want users to be able to create tasks, edit them, mark them as done, set priorities, add due dates, and see which ones are still pending or overdue. Please make the experience clean and simple, with a dashboard that helps people understand what still needs attention. It should also send browser notifications for tasks that are coming up or late.

Please include secure authentication, a working backend and frontend, and make sure the app feels polished enough to use for real. If you need to check current docs or best practices while building it, go ahead and look them up.
