You are implementing state management for a Flutter feature using Cubit + RxDart.

## Three Patterns by Use Case

Choose based on the skill argument, if one was given, or on the context of the feature:

- `simple` — basic async operations (load data, submit form)
- `stream` — real-time data via RxDart BehaviorSubject
- `event-bus` — cross-module communication via Broker
