12	* Excludes products from Disco discounts when they are managed by other plugins.
13	* To exclude a product, hook into `disco_exclude_product_from_discount` and return true.
14	*
15	* Example:
16	* add_filter( 'disco_exclude_product_from_discount', function( $exclude, $product_id, $product ) {
17	* return my_plugin_is_special_product( $product_id ) ? true : $exclude;

25	* is set dynamically at runtime via set_price(). Applying a Disco discount

31	*
32	* Root cause: disco_discounted_price() (priority 999 on woocommerce_product_get_price)
33	* calls CalcFactory::get_product_price() which always fetches the base price from post
34	* meta (_price), ignoring the runtime price TM EPO set via set_price() to include extra
35	* options. This strips the options cost from every get_price() call in the cart.
36	*
37	* Fix: after TM EPO populates cart items from session we record each product object's
38	* extra options price keyed by object hash. A filter at priority 1000 then adds it back
39	* after Disco has applied its discount to the base price.
