+@* Dispatch page: reads DriverInstance.DriverType and renders the matching typed editor
+   via <DynamicComponent>. Falls back to the legacy DriverEdit for any type not yet in
+   the map. The route collides with DriverEdit.razor's identical directive — that's
+   intentional. Task 3.4 removes the route from DriverEdit.razor. Blazor route conflicts
+   are runtime, not build-time, so the build succeeds now. *@
