## Extension points
A later resource-observation service may produce this snapshot while moving
ResourceLoader/cache request ownership out of the loader. The value contract
must remain independent of that service and of generic callback frameworks.
`M2StaticBuildResourceObserver` now produces the static phase. A later animated
observer may produce the first phase. The value contract remains independent of
both producers and of generic callback frameworks.
