;; Conformance fixture: machine/parallel-compound-region
;;
;; A `:type :parallel` machine where one region's state-tree is itself a
;; compound state (declares `:initial` + nested `:states`). The region's
;; value inside the snapshot's `:state` map is a vector path INSIDE that
;; region; sibling regions are unaffected by the compound region's
;; transitions.
;;
;; Per [005 §Parallel regions](../../005-StateMachines.md#parallel-regions),
;; [§Snapshot shape](../../005-StateMachines.md#snapshot-shape), and
;; rf2-l67o (Nine States Stage 2).
