26	* update_order_review AJAX response. Because these values change
27	* each request, WooCommerce always sees the fragment as "new" and

29	* update — creating an infinite loop.
30	*
31	* This class strips those dynamic scripts from the fragment and
32	* moves them to a separate fragment key so the payment HTML stays
33	* stable between requests.
