+
+`parentId` is the category id. Creates `article` + `articletext` (company default language) + `categoryarticle` in one transaction. Allocates `sku` via `getnextnumberwithprefixandpadding` (`type` `sku`; creates `numbers` row with empty prefix if missing). Default unit `pc` is ensured if missing (`unitamount` 1, `weight` 0).
+
+Auth via `resolveCategoryAccess(googleAuthId, parentId)` — `Parent not found` / `Not authorized`.
