Angular Signal Forms: From event pipelines to signal-driven state

Angular Signal Forms introduce a state-first approach to form management, replacing event-driven pipelines with reactive signal-based state. Instead of coordinating validators, control states, and UI updates through event chains, developers define a data model as a signal and declare validation rules as constraints on that state. Angular then derives validity and updates the UI automatically. The API includes a form() function, built-in validators like required and email, and interoperability tools (compatForm, SignalFormControl) for incremental adoption alongside existing reactive forms. Currently experimental, Signal Forms align with Angular's broader Signals-based architecture shift.
