biplob004/study_wizard — reverse-engineered prompt

Build me a simple AI study site from this repo that feels polished and easy to use. I want people to be able to register, sign in, land on a welcome page, see their overall progress, browse the course catalog, and then open a course like Vocabulary.

Inside Vocabulary, there should be a calm learn mode where you can tap a word, see a bigger picture, hear the audio, move through cards, and have studied words count toward progress. There should also be a practice mode with 15 scored rounds using mixed activities like matching, picking the right picture, unscrambling, and listening. Scores and progress should save to the user account, separately for each course, and practice should favor words the learner has not seen much yet.

Please also include the daily habits tracker on the landing page so each user can add habits, check them off each day, build streaks, and earn points. If AI answer checking is available, use it, but make sure the app still works without an API key. Keep it easy to extend with new courses later, and make local setup straightforward.
