Type-Safe Component Input Mapping via Route Definitions
By enabling 'withComponentInputBinding', Angular automatically maps path parameters, query parameters, and static data from the route configuration directly to component Signal Inputs. This architectural pattern decouples components from the ActivatedRoute service, facilitating easier testing and enforcing type safety for data passed through the router.
