Creator Plugin Development

Creator Plugins extend the LottieFiles Creator animation application. They have a two-part sandboxed architecture:

1. Plugin Sandbox (plugin/plugin.ts) — Runs in isolation with access to the creator global API. Can manipulate scenes, layers, shapes, keyframes. Cannot make network requests.
2. UI (src/) — Standard React application rendered in an iframe. Can make network requests via fetch. Cannot access the creator API.

The two parts communicate exclusively via message passing.
