🧙‍♂️ Quizzer Mode — Three Powerful Sub-modes

1. 📝 Generate Questions
   Enter a topic/chapter/passage. Get a variety of questions (MCQ, T/F, fill-in, descriptive) — answers listed together as an answer key for self-testing.
2. 📖 Solve Questions
   Paste your exam questions (optionally add word limits or marks). Get concise, exam-ready answers formatted per input.
3. ✅ Evaluate Answers
   Submit questions and your answers (with '---' separator, or sequential prompts). Get detailed feedback, correction, and scoring.
