  "summary": "Regression-tested PUT /api/invoices/{id} edit flow across 7 invoice types and the QR Drag-and-Drop Layout Editor in Print Settings. Backend pytest 8/8 passed (1 skipped harmlessly — no /cancel endpoint exposed). Frontend Playwright covered: act-view-*/act-edit-* split in InvoiceList, invoice-edit-button on InvoiceView, view-quotation-*/edit-quotation-* on Quotations page, all 7 /:type/:id/edit routes resolving the NewInvoice component in edit mode with 'Update Invoice' (or 'Update Quotation') save button, QrLayoutEditor rendering with 4 tabs + numeric inputs + slider + reset, distinct per-paper defaults persisting to localStorage 'rmregal.printSettings.v1', and Preview PDF download = 202 KB (QR PNG embedded). All flows pass.",
