 ## How it was built
 
-Pages are selected server-side from Crom GraphQL API with: URL on `scp-wiki.wikidot.com`, Wikidot category `_default`, `is_hidden = false`, and `is_user_page = false`. Per page the crawler requests the free fields plus the costly `source`, `summary`, and `alternate_titles`; it skips `text_content` (rendered HTML) and `attributions`. Timestamps are stored as UTC. See [`src/scp_dataset.py`](src/scp_dataset.py).

 **Takeaway.** Themes form clear clusters. The strongest pairing is 'sapient' + 'humanoid': entity descriptors (humanoid / sapient / alive) co-occur tightly, forming a 'monster' cluster distinct from the genre tags.
