The user wants you to generate a complete document JSON from scratch.

Produce a full DOCX JSON wrapped in a ```json code block:

- Use a `Report` root with one or more `Section` children
- Start with a level-1 `Heading` as the document title
- Mix component types for visual interest: Headings, Paragraphs, Tables, Lists, Statistics
- Include `Header` and `Footer` if appropriate for the document type
- Use `Columns` for side-by-side comparisons or multi-column layouts
- Aim for 3–6 sections with varied content
