Region

A persistent spatial zone within a runtime. Regions divide the runtime into distinct spatial zones with different interaction characteristics and anchor behaviors.

Primary regions:

• carry — user-following interface space; anchored to the member; high interaction density; persists during movement
• field — world-anchored environmental space; spatially fixed; tied to locations; lower interaction density

Allowed:

• carry region
• field region
• [name] region

Forbidden:

• zone (too generic; use region)
• layer (acceptable in technical prose; not the product noun)
• area (too vague)
• pane (implies flat document layout)

Notes:

• Regions are the top structural division within a runtime. Each region contains decks.
• Carry and field are the canonical region names. Do not introduce additional region names without extending this definition.
• "Carry region" and "field region" are the qualified forms when disambiguation with other carry/field usages is needed.
