Angular Signals are not a replacement for RxJS or NgRx. Use Signals for local, synchronous UI state, RxJS for async and time-based workflows, and NgRx for shared, long-lived domain state. Migrate incrementally by moving component-level BehaviorSubject stores to Signals while keeping HTTP, debouncing, and side effects in RxJS.
