Architectural note

FlowRedux takes a Redux-inspired approach: states are flat sealed interfaces. It is good for reactive UIs driven by Kotlin Coroutines Flow, but it does not implement the UML statechart model (no hierarchy, parallel regions, or pseudo states).

Tinder StateMachine is a minimal library — a flat FSM with sealed-class type safety. Suitable for simple use-cases where a full statechart is not required.
