# AppearanceControlsRoot
`AppearanceControlsRoot` exposes the slot contract returned by `useAppearance()` as a structural
primitive. Use it when you want reusable appearance controls with custom presentation.
The root owns selection-derived presentation decisions, including `showIndependentCorners`.
That state becomes active when the selected node explicitly uses independent corners or when an
imported node contains unequal corner values with a stale uniform flag. Consumers should render
from this state rather than maintaining a parallel local expansion ref.
Multi-node independent-corner toggles and per-corner commits are grouped into one undo entry.
