"""
Minimal NPOV-Onset loader: read the three tables, reconstruct the 688 matched pairs,
and show how to pull the article text for a snapshot from the MediaWiki API.
Works directly on the CSVs in this folder (no `datasets` install needed). The Hugging Face
equivalent is one `load_dataset(...)` call per config — see the dataset card.
