Field Placement

A spatially anchored placement for a surface. Field placement allows a surface to appear at a real-world or world-field anchor without changing surface identity.

Allowed:
- field placement
- field-anchored surface

Forbidden:
- map page
- AR-only panel

Notes:
- Field placement is persisted as surface placement metadata.
- Runtimes decide how to render the placement for web, Android, or XR.
