* Fix – Address a fatal error when displaying order details with store credit on orders without a payment method
* Fix – Return reserved store credit to the customer's available balance when a partial-payment order fails, not only when it's cancelled
* Fix – Refund the full store credit when a partial-payment order is cancelled, instead of capping it to the amount charged to the gateway
* Dev – Allow third party code to register custom events for store credit wallet transactions (experimental)

* FIX: Bizum on the payment page (Bizum InSite) did not send the description to Redsys. The actual charge from the modal is made through the REST API (trataPeticionREST), and that request did not include the DS_MERCHANT_PRODUCTDESCRIPTION parameter, so the configured "Redsys Description" (for example "Order ID") reached the Redsys panel empty. The description is now computed from the selected setting and sent in the REST request.
* UPDATE: The countdown in the Bizum payment-page modal showed 7 minutes. It now correctly shows 5 minutes, and the server-side time control that redirects to the checkout has been adjusted accordingly (60 iterations * 5 seconds = 5 minutes).

* Add agentic development guidelines and fix E2E tests.
* Ensure point redemption is tracked correctly on orders made with Store API.
* Fix – Points and Rewards messages now display correctly for variable products with more than 30 variations loaded via AJAX.
* Fix – Replace hardcoded background color on earn points message with inherit to support dark block themes.
* Fix STORMA-3: Points Log per-page Screen Option not taking effect.
* Fix: Allow HTML formatting to display in the Cart/Checkout blocks.
* Move WC Blocks integration hook into `init` method to register earlier.
* Prevent deprecation notices relating to wc_enqueue_js.
* Stop passing null into wp_kses() from Cart Store API extension.
* Tweak – WC 10.8 compatibility.
* Tweak – WP 6.9 compatibility.
* Update node to `lts/iron` in `.nvmrc`.
