🎯 What this extension does

When you study on Coursera, LearningNote opens as a side panel on the right and automatically understands:
- Which course you are on
- Which module/week you are in
- Which lesson (video / reading / quiz / exam / assignment / discussion) you are viewing

It then gives you three focused workspaces:
- **Context** — big picture overview of all your notes in the course
- **Notes** — fast, structured note-taking for the current lesson
- **AI Quiz** — AI assistant to help you reason about quiz questions

All notes and settings are stored locally in chrome.storage.local. There is no separate backend server.

    - Quiz / Exam: shows a “Open AI Quiz” button instead

🤖 AI Quiz tab — ask AI, stay in control

LearningNote does **not** auto-answer quizzes. Instead, it:
- Extracts quiz questions and options from the current Coursera page
- Lets you ask AI for:
  - Best answer(s) per question
  - Clear explanation
  - Why the other options are wrong

Key features:
- **Multiple AI providers**:
  - Quick AI (via Pollinations, no API key required — best effort, for quick use)
  - Gemini, Groq, DeepSeek, Mistral, OpenRouter (user provides API key)
  - Custom OpenAI-compatible endpoint (base URL + model + key)
- **Ask AI per question** or for **all questions at once**
- Answers are highlighted inline on the question (with support for multi-select)
- Explanations are shown as draggable cards, with expand/collapse and close
- “Explain in Vietnamese” mode re-asks the AI in Vietnamese, not just raw translation
- **Save entire quiz** as a single structured note:
  - All questions and options
  - Compact answer key (Q1=A, Q2=D, …)
  - Explanations in English and/or Vietnamese
