3	* WooCommerce Germanized Compatibility
4	*
5	* Handles two integration points between WPFunnels and Germanized:
6	*
7	* 1. Checkout submit button – Germanized hides the default WC submit button via
8	* woocommerce_order_button_html filter and renders its own block at the end
9	* of woocommerce_checkout_order_review. On WPFunnels funnel checkout pages
10	* this means the button lands outside WPFunnels' payment section. We tell
11	* Germanized to disable its checkout adjustments by defining the
12	* WC_GZD_DISABLE_CHECKOUT_ADJUSTMENTS constant before Germanized's own
13	* mechanism reads it (woocommerce_before_checkout_form priority -999).
14	* Germanized then:
15	* - stops hiding / relocating the WC order button,
16	* - moves legal checkboxes to woocommerce_review_order_before_payment
17	* so they still render inside WPFunnels' payment section, and
18	* - outputs a wc_gzd_checkout_disabled hidden field so AJAX order-review
19	* requests also carry the disabled flag.
20	*
21	* 2. Offer order confirmation – Germanized removes the standard WC order-
22	* notification hooks and sends its own confirmation via the
23	* woocommerce_payment_successful_result filter, which never fires for
24	* WPFunnels' AJAX offer acceptance. We hook into wpfunnels/offer_accepted
25	* and call Germanized's confirm_order() directly for child/separate orders.
