Pratham-Mishra225/QuizCraft ? reverse-engineered prompt

Build me a full stack quiz app called QuizCraft where people can sign up, log in, and create quizzes in a few different ways.

I want a clean dashboard where users can make quizzes manually with multiple choice questions and explanations, or ask AI to generate a quiz from a topic and difficulty level. There should also be a PDF upload flow that turns a document into a quiz and shows where each answer came from in the file. Users should be able to share public quizzes with a link, take quizzes, and see their score right away.

Please make the results page show which answers were right or wrong, the correct answers, explanations, and quiz history over time. Keep authentication secure with cookie based sessions, and make the app feel polished, fast, and production ready. If you need to check current docs for any libraries or APIs, go ahead and look them up online.
