	13	+ * Replace the package rates with free shipping when a campaign grants it.
	14	+ *
	15	+ * The paid rates are dropped rather than kept alongside a free one. Leaving
	16	+ * them in place only offers free shipping, it does not apply it: WooCommerce
	17	+ * keeps charging whichever rate is already chosen in the session, and the
	18	+ * customer has to pick the free one by hand. That is impossible on the cart
	19	+ * page unless the shipping calculator is enabled, so the same campaign looked
	20	+ * applied at checkout and ignored in the cart.
	21	+ *
	22	+ * A free shipping method the merchant configured themselves is kept in
	23	+ * preference to ours, so their own title and settings survive.
