Compares concrete APIs by showing a working sample app: canvas clocks that replace ValueAnimator with Animatable + launchedEffect driving coroutine-based animateTo, image transitions using AnimatedVisibility and animateState (float/dp/color) with spring defaults, a list→detail screen built with AnimatedContent* and an example card coordinated by UpdateTransition for alpha, elevation and translation. Notes that low‑level coroutine scopes can trip you, MotionLayout‑style choreography is not yet available, and many APIs remain experimental but functional.
