Summary
Routes CSS transition properties to Core Animation behind
IOS_CSS_CORE_ANIMATION, starting withopacity.CSSPlatformTransitionProxyis a stateless shared router: per property it picks the platform or the C++ loop and forwards the raw JS value to the platform, never holding a platform value type.REACSSPlatformProps(routing predicate, value parsing, CA conversions, timing) andREACSSPlatformTransitions(the CALayer applier).With the flag off there is no behavior change.
