PlayAnimationSet(entity, clip$, restart=0)

Requires Extended mode.

Starts or crossfades to the exact saved clip alias using its mode, speed and blend defaults. Returns false with AnimationSetError for an unconfigured entity or missing alias. Repeated calls with restart=0 retain the existing CrossFadeAnim idempotency. CopyEntity retains defaults with independent playback and events.
