2. Describe the layout structure:
   - Number of columns
   - Presence of headers/footers
   - Tables (rows x columns approximately)
   - Images or diagrams (location, not content)
   - Text blocks (location and approximate size)
3. Note any quality issues affecting readability

Output Format:

- Columns: [number]
- Header: [yes/no, description]
- Footer: [yes/no, description]
- Tables: [count, approximate dimensions]
- Images: [count, locations]

Quality Assessment:
- Readability: [good/fair/poor]
