Smart Match rules
- GTIN / UPC / EAN must match exactly when present.
- Brand + MPN or Brand + model used only when GTIN-family IDs are absent.
- Condition (new / refurbished / open-box / used) is part of the match key.
- Size and color are part of the match key — never merged across variants.
- Title similarity alone never groups offers.
