4/// Selection opt-out marker.
5///
6/// Everything in an editor subtree is selectable by default. Wrapping a subtree in
7/// `SelectableComponent::off()` excludes it from editor selection — clicking a descendant
8/// will not move the gizmo, update the inspector context, or trigger `SelectionChanged`.
9///
10/// Used by editor-owned helper subtrees to self-exclude UI from scene picking.
