Node
Node is any field definition that can be placed in Fields. Authors normally create nodes with constructors such as Text, Select, Group, or Array and use their concrete fluent methods before adding them to a field list. The interface is sealed so Ridu can snapshot every supported field safely.
ChildrenDraft
ChildrenDraft owns a detached slice. Committing snapshots again, so retained drafts cannot mutate published graphs. Structural edits are explicit.
