+
+## Visual Elements
+
+- Realistic photo perspective: top-down view of study desk
+- Hand holding blue ballpoint pen, actively underlining
+- Extremely dense handwritten content, filling entire page
+- Red pen annotations: circles, underlines, stars, boxes
+- Yellow highlighter marking key terms
+- Correction marks, cramped notes squeezed into margins
+- Simple hand-drawn symbols: → * ✓ ✗ !
+- Varying pen pressure creating lighter and darker strokes
+
+## Typography
+
+- Authentic student handwriting
+- Messy but readable, clear structure maintained
+- Varying font sizes (large titles, small body, tiny margin notes)
+- CJK optimized
+
+## Content Structure
+
+Three-section layout:
+
+### Top Section
+- Core topic (circled multiple times in red)
+- First section title + 3-4 key points
+- Arrow connections, red underlines
+
+### Middle Section
+- Second section title (red pen box)
+- Numbered steps ①②③
+- Specific methods and supplementary notes
+
+### Bottom Section
+- Third section title (red star)
+- Time points / key metrics
+- Key quotes / core tips (tiny corner notes)
+
+## Best Layout Pairings
+
+| Layout | Compatibility | Use Case |
+|--------|---------------|----------|
+| sparse | ✗ | Not suitable - style requires dense content |
+| balanced | ✓ | When content is lighter |
+| dense | ✓✓ | Best fit - knowledge notes, summaries |
+| list | ✓✓ | Step checklists, rankings |
+| comparison | ✓ | Comparative analysis |
+| flow | ✓ | Process flows |
+| mindmap | ✓✓ | Mind map notes |
+| quadrant | ✓ | Quadrant analysis |
+
+## Best For
+
+- Study guides, exam notes
+- Knowledge organization, framework summaries
+- Tutorial summaries, quick notes
+- "Top student notes" style content
+- Knowledge sharing requiring authentic feel
+
+## Style Rules
+
+### DO ✓
+- Keep content extremely dense
+- Use simple symbols (→ * ✓ ✗ !)
+- Annotate key points with red pen
+- Include correction marks
+- Squeeze tiny notes into margins
+
+### DON'T ✗
+- Use complex emojis
+- Leave too much whitespace
+- Make neat, tidy layouts
+- Add colorful decorations
+- Include cartoon elements
