## Usage

```python
import json
import zipfile

# Load article metadata
with open('metadata_natcomm_2512_001/metadata/s41467-025-65722-y.json', 'r') as f:
    article = json.load(f)

# Access sections with hierarchy
for sec_id, sec_info in article['section_set'].items():
    if sec_info['level'] == 2:
        print(f"Section: {sec_info['title']}")
    else:
        print(f"  Subsection: {sec_info['title']}")

# Access figures with citations
for fig_id, fig_info in article['image_set'].items():
    print(f"{fig_id}: {fig_info['caption']}")
    print(f"  Cited in: {[c['section'] for c in fig_info['contexts']]}")
```
