Struct ViewSnapshot 

pub struct ViewSnapshot { /* private fields */ }

Read-only, cheaply-cloneable snapshot of ViewState.

Created once per frame by the view system and shared with all stages via StageContext. Clone is an Arc bump.

Stages and output consumers receive ViewSnapshot, not ViewState.
