+     * Override to fix free product rewards for manual_membership (subscription) programs.
+     *
+     * Odoo's base _computeUnclaimedFreeProductQty returns Math.min(available, freeQty).
+     * `available` = qty of the reward product already in the current order.
+     * For subscription programs (e.g. Makan Pagi Gratis), the free breakfast product is
+     * NOT in the order yet — so available=0, freeQty=0 and the reward is never shown.
+     *
+     * Fix: after the base getClaimableRewards runs, we re-evaluate manual_membership
+     * programs that were silently skipped and inject their product rewards using the
+     * raw point-based qty (points / required_points), so the cashier can select them
+     * from the Rewards popup and the product is added to the order automatically.
