 - Audit `EnvelopeGenerator.Server/EnvelopeGenerator.Server.Client/Services/` for unnecessary request/payload remapping and remove redundant mappings where direct request DTO usage is safe; review client HTTP methods end-to-end for similar avoidable transformation layers.
 - Centralize dependency injection registrations into dedicated extension methods/modules (especially server + client service registrations in `Program.cs`) to reduce startup composition sprawl and improve maintainability.
 - Refactor `EnvelopeGenerator.Server/EnvelopeGenerator.Server/Controllers/PdfRenderController.cs` + matching client service contract to remove JSON/base64 `byte[]` transport for PDF rendering; prefer binary streaming (`application/octet-stream` or multipart), avoid `data:` URL bloat where possible, and validate end-to-end memory/latency behavior with large PDFs.
+- Establish a DevExpress toast-based notification architecture using `DxToastProvider` + `IToastNotificationService` (tab/page-scoped provider strategy, standardized `ToastOptions` factory, and severity-to-style mapping) so sender/receiver flows show consistent, non-duplicated, actionable feedback.
