Data
Download from Kaggle (needs an API token from https://www.kaggle.com/settings):
pip install kaggle
python data/download.py
Expected layout after download:
data/artwork_metadata.csv 3,997 rows — filename, religion (1,000 each of
buddhism / christianity / hinduism; 997 islam),
sub_religion, artist, title, year, place,
source, source_id, source_url, image_url
data/images/ the 3,997 images, filenames match the CSV
(download.py flattens Kaggle's images/images/)
Generated later by the pipeline (gitignored):
data/masks/ guarded background masks + verdicts.csv
data/features/ one parquet per feature family
