/**
 * Transition status state machine for components that animate between an
 * `open` boolean and actual mount/unmount. Keeps the element mounted while
 * exit animations run and introduces an optional stable `idle` phase.
 *
 * Adapted from MUI Base + Floating UI examples:
 *  - Source: https://github.com/mui/base-ui/blob/6fd69008d83561dbe75ff89acf270f0fac3e0049/packages/react/src/utils/useTransitionStatus.ts
 *  - Originally based on https://github.com/floating-ui/floating-ui/blob/7c33a3d0198a9b523d54ae2c37cedb315a309452/packages/react/src/hooks/useTransition.ts
 *
 * States (transitionStatus):
 *  - "entering"  : just entered (initial frame of enter) OR re-entering to reach "idle".
 *  - "idle"      : stable open (only when `enableIdleState === true`).
 *  - "exiting"   : exit animation is running; element still mounted.
 *  - undefined   : closed (unmounted) OR stable open when idle state is disabled.
 *                   When `enableIdleState` is false we clear the label after
 *                   the first frame so styling can rely purely on `mounted`.
 *
 * Distinction:
 *  - `mounted` tells you whether to render DOM.
 *  - `transitionStatus` tells you which phase-specific classes to apply.
 *
 * Frame separation: state changes that must trigger CSS transitions are
 * scheduled with `requestAnimationFrame` so the browser sees distinct style
 * mutations across frames (avoids missed transitions due to batching).
 *
 * @param open              Controls visibility lifecycle.
 * @param enableIdleState   Insert a persistent "idle" phase after entering.
 * @param deferExitingState  Delay entering the exit phase by one frame to allow
 *                          measurement / layout work before applying exit styles.
