"""Generate first-stage Cocos-facing scene data from source evidence.

The Cocos 4 alpha CLI on this machine cannot currently build because of a
native ABI mismatch. This script therefore writes source-backed scene data that
can be consumed by a later Cocos 4 scene writer once the CLI/runtime is fixed.
