The staging editor was built with neither --models-tag (no models on the
staging CDN) nor VITE_MODELS_SOURCE, so modelsSourceConfig() returned null,
no model3d handler was installed and every 3D ensure answered "(unserved)"
despite the chunked packages3D ingest being complete on the staging registry.
- build-editor.mjs: --models-source <cdn|registry> → VITE_MODELS_SOURCE
- deploy-staging.yml: editor builds with --models-source registry
- release.yml: prod editor builds with --models-source registry (libs/0016 §6
step 4); MODELS_TAG now only feeds the demo build, which has no closed API.
Prod rollout order: split-lib-kinds + packages3D ingest on prod BEFORE the
next release tag — prod's registry currently has 0 model3d libs.
