+/** @odoo-module
+ *
+ * ClosePosPopup patch — surface a READ-ONLY Laundry Settlements panel
+ * in the POS closing popup so cashiers and managers can see how much
+ * was collected via the laundry settle-dues flow during this session,
+ * grouped per journal.
+ *
+ * NON-CASH settlements create account.payment records (not pos.payment),
+ * so they don't naturally appear in the closing popup's per-method
+ * breakdown. CASH settlements DO appear there (via statement_line_ids
+ * in expected cash). This panel makes both visible side-by-side so the
+ * cashier can reconcile drawer vs. settlement collections.
+ *
+ * IMPORTANT: this is purely informational. It does NOT inject into the
+ * cash-counted/expected math, does NOT create accounting entries, and
+ * does NOT modify settlement amounts.
