Customiser support finishes
Delete a support finish image
Clears one of the support finish's image slots and deletes the stored
file, returning a receipt naming what was removed and the support finish
as it now stands. Requires customisers:write and an Idempotency-Key.
Overview
Deleting from a slot that holds no image answers 404.
Deleting the texture image of a finish whose finish_kind is texture
is refused with 422 texture_image_required: the finish renders from
that image, and the storefront could not draw the backboard without it.
Change finish_kind on the finish first, then delete the image.
The delete clears the customiser's cached storefront configuration and
runs the advisory language sync, and never regenerates Shopify products,
product images, or the product cache.
