Shopify Catalog Cleanup

Fixing the debris an audit found. This is the mutating counterpart to shopify-catalog-audit (which finds problems) and shopify-seo-metadata (which fills missing metadata). Everything here writes to the catalog, so the whole skill is built around one rule: preview the count, then mutate.

Store access

Lane A: custom-app token (scriptable). In Shopify admin: Settings → Apps and sales channels → Develop apps → create an app → grant read_products and write_products, install, copy the Admin API access token. Export it; never write it to a committed file:

export SHOPIFY_STORE="your-store.myshopify.com"
export SHOPIFY_ACCESS_TOKEN="<your Admin API access token>"   # env, not disk
