samirkharal37-dotcom/Mern-Task-Dashboard ? reverse-engineered prompt

Build me a full stack task dashboard where people can sign up, log in, and manage only their own tasks.

I want a clean, modern interface with a professional login and registration page, then a dashboard where users can add tasks, see all their tasks, edit them, delete them, and mark them as completed or pending. Each task should support a priority like high, medium, or low, and the layout should look good on desktop and mobile. Please make the design feel polished with nice colors, cards, spacing, and simple hover effects.

On the backend, set up secure authentication with hashed passwords and JWT so task actions stay protected. Store users and tasks in MongoDB, and keep each user’s data separate. Use the frontend and backend folders already in the project, wire everything together, and if you need current setup details, check the docs or look up anything missing online.
