Node class sealed

Runtime scene-graph node (hierarchical TRS).

Notes:

• All nodes (including groups) have a real Transform2D.
• Group nodes structurally own children (no groupId).
• IDs are intended to be globally unique within the document.
• Optional user-facing display names live in name.
• Optional higher-level group semantics live in GroupNode.behavior. Core runtime does not interpret product/domain behavior types directly.
• Sibling order is paint/stack order: earlier siblings paint behind later siblings.

Available extensions

• NodeFields
• NodeMutations

Annotations

• @Freezed.new(unionKey: 'runtimeType')
