Surface

A physical, geometric, or domain-specific working area. Use the ordinary
meaning when it is needed, such as a Paint drawing surface, canvas surface, or
touchscreen surface.

Surface is not an Elonn platform primitive. It does not name a persistent
Runtime container, a Service-backed presentation unit, or an Object carrier.
The former surface.elonn.local model must not be used to describe current
World or Runtime behavior.

For the result of a member's Call, use the Results pane and its Findings. For
opened content, use the Object placed on Carry. For Service-produced content,
use Object or the specific domain noun.
