+/** @odoo-module
+ *
+ * Pricing hook (PREPARE-ONLY).
+ *
+ * Reads the per-type and per-attribute extra_price values for the
+ * current order. Returned values are NEVER applied to the order.
+ * This module exists so future pricing logic can plug into a single
+ * stable surface without touching order.lines / pricing / taxes today.
+ *
+ * Usage example (NOT wired anywhere):
+ *   import { computeLaundryExtras } from "@laundry_management/js/laundry_pricing_hook";
+ *   const { typeExtra, attributeExtras, total } = computeLaundryExtras(pos, order);
