Missing product_type data breaks discoverability & filteringhigh

All 1,250+ products have empty product_type fields, preventing customers from filtering by category (e.g., novels, magazines, textbooks, photo books). The store carries diverse content types (manga, photo collections, magazines, educational materials) but offers no way for shoppers to narrow results.

Customers browsing 1,250+ SKUs without category filters face friction, reduce browse time, and abandon the site; lack of structured product taxonomy also harms internal search ranking and SEO.
