Optionalextrinsic?: booleanSet when the surface is sized by its container (e.g. a user-resized embed) rather than its intrinsic content, so the surface can fit its content to the box instead of sizing to it.
OptionalnodeId?: stringThe graph node this surface renders, which is what its contributed actions are filed under.
Distinct from attendableId: a companion shares its host plank's attention id, so the two are
the same for a primary plank and differ for a companion. A surface that reads its own actions
from attendableId therefore renders the host's toolbar when it is a companion.
