Clayzo animation shipping

Always read shipping animations.

Before final output, read both previewing work and self-review. If the artifact loops, also read loop design.

Ship the exact reviewed revision. Confirm renderer coverage, fonts and assets (audio included), playback behavior and states, sound, web playback cost, deployment paths, and export constraints. Use clayzo commands and the public player entries: ClayzoPlayer, <clayzo-player> and createPlayer() / PlayerHandle on the web, and the Swift ClayzoPlayer in apps. Playback runtimes never authenticate.
