Mirrors Admin GraphQL collectionRemoveProducts. Body: { productIds: string[] }, same as POST.

ASYNCHRONOUS, unlike the POST. It returns { job: { id, done } } and done: false is the NORMAL successful answer — the products are still in the collection at that moment. Do not retry on done: false; re-read the collection instead.

Only works on a CUSTOM (manual) collection; rejected on a SMART one.

• Write — changes a live store immediately; needs a write-scoped token.
