## Parameters
- **Depth:** [DEPTH — e.g., 2 levels, 3 levels, 4 levels]
- **Focus:** [FOCUS — broad overview / deep dive on [SUBTOPIC]]
- **Audience:** [AUDIENCE]

- Sub-point
  - Detail
  - Detail
- Sub-point

## Main Branch 2
...
```

## Mind Map Structure

### Root Node
[TOPIC]

### Main Branches (6–8 branches)
Organize the topic into logical major categories. Examples for [TOPIC]:
- [BRANCH_1]
- [BRANCH_2]
- [BRANCH_3]
- [BRANCH_4]
- [BRANCH_5]
- [BRANCH_6]

### Sub-branches
For each main branch, include 3–5 sub-points with concrete details.

### Leaf Nodes
For complex topics, add a third level with specific examples, tools, or data points.

## Output
1. **Full Markmap Markdown** (copy-paste ready for markmap.github.io or VS Code Markmap extension)
2. **Plain-text summary** of the top 5 insights from the mind map
3. **Suggested next steps** — what to explore deeper based on the map

Make the structure genuinely useful and comprehensive. Every branch should add real value, not just fill space.
