    'customProductJson' is the default JSON
    'option_*_exists' is the cross-reference for sold out

    'product_available' is default behavior (will become null in the case of the parent Product)
    'default_variant_id' is default behavior (will become null in the case of the parent Product)

    'product_media' is the default media (will be overridden in the case of the parent Product)
    'variant_images' is the default variant images
    'image_alt_base' is the base for the Alt Tag to assign images (ignored in the case of the parent Product)

      'soldOutOptions' is if an entire Parent Option is sold out based on Child
      'missingChildren' is if a Child Product does not exist (we remove the Parent Option)

      'customProductJson' replaces the Product Variant default JSON

      'option*SelectedValue' replaces the product.selected_or_first_available_variant

      'option_*_exists' is the cross-reference for sold out

      'product_media' is reset to build on Child Products
      'image_alt_base' is set to blank since we will be using Child Products
