Space nodes define bounded contexts, structural containers, or higher-level areas in which other UPDL nodes can be organized.
Typical Responsibilities
Represent a scoped environment or domain surface.
Hold related entities, events, and actions together.
Provide a top-level frame for export or generation workflows.
In the broader platform direction, a space node can represent a knowledge area, a design-time container, or another structured scope instead of only a 3D scene.
