Framer Motion layout prop and React 18 conditional rendering interoperability

Goal: Achieve deterministic layout animations in Framer Motion (v10+) when components are conditionally rendered, ensuring repeatable behavior across renders in a development environment with hot module replacement (React 18).

Uncertainty arises because the layout prop depends on synchronous DOM measurements that may be delayed by React 18's automatic batching and concurrent rendering priorities, while HMR resets motion values and can break animation continuity.

• Does the layout prop maintain consistent enter and exit animation timings when a component toggles under React 18's automatic batching?
• How can motion value state be preserved across hot module replacement to retain animation repeatability without manual persistence?
