Build me a clean, modern DSA practice tracker web app where I can organize my coding prep by topics, subtopics, and questions. I want to be able to add, edit, delete, and reorder everything easily, mark questions as solved, and see progress update right away in a dashboard with stats and a progress ring.

Make it responsive for both mobile and desktop, with a light and dark theme that saves my preference. Include a nice sidebar on desktop and a slide out menu on mobile. I also want a guest mode so people can preview the sheet without signing in, plus sign in and cloud sync for logged in users so each person has their own saved curriculum in MongoDB.

Let me attach problem links and video solution links to questions, choose difficulty levels, and reset everything back to a default curated DSA sheet with one click. If you need anything unclear, look up the current docs online first.
