Build me a simple task manager web app that feels clean and modern, with a nice polished interface.

I want to be able to add tasks, mark them as done, edit them, and delete them. Please include basic filtering so I can see all tasks, only active ones, or only completed ones. It should work smoothly on desktop and mobile, and the design should be easy to use without feeling cluttered.

Use a React based front end with plain HTML, CSS, and JavaScript where it makes sense. Keep the code organized and easy to understand, since this is part of a collection of small AI assisted experiments. If there are any sensible small improvements like saving tasks locally in the browser, add them too.

Make it feel like a real app, not just a demo. If you need to look up current docs online, go ahead and do that.
