Shopify Category Taxonomy

Two jobs that chain together: assign a product's Standard Product Taxonomy category (Part 1), then fill the category metafields that category exposes (Part 2). You cannot do Part 2 until Part 1 is true: the "Category metafields" panel only exists once a product is assigned to a category. Bulk CSV data work lives in the sibling shopify-matrixify; the one thing Matrixify cannot do is mint the reserved value metaobjects Part 2 needs, which is the entire reason this skill exists.
