Checked 2026-09-24: the ProductCatalog template has a catalog-enabled Products list, Documents, Offers, Reviews, Providers; the publishing site serves category and item pages through the catalog connection (/sites/AngelsWorks/solar/...). Gaps against SharePoint's template: ContentType.CatalogProduct carries solar columns (PanelType, PowerW, VocV ...) - they belong on the generated ContentType.SolarPanel only, so the template stays generic; ProductCategory is a text path, SharePoint drives catalog navigation from a Taxonomy column bound to the Product Hierarchy term set; SKU should be SharePoint's Item Number; no Rollup Image, so category and item pages show no picture. Impact-scout the CatalogProduct change first (seed, views, rollups, tests).
