Catalog Attribute Normalizer
Taxonomy-grounded catalog attribute normalizer — no fabricated Google/Shopify category IDs, ever. Titles and raw attributes in, canonical attributes plus Google/Shopify/Amazon category paths out. **Reliability by design:** deterministic size/color canonicalization with provenance marking (canonicalized vs extracted), retrieval-grounded classification (~92% exact-match on our Google/Shopify eval set), and taxonomy leaf IDs returned only when verified against the real taxonomy
