isAutographScopeContainer

Whether this element is an Autograph scope container — a wrapper carrying AUTOGRAPH_SCOPE_IDENTIFIER_PREFIX in its identifier.

Load-bearing in two places, for opposite reasons: deepestAccessibilityHitPath exempts such a node from the containment gate so it cannot prune a child drawn outside it, and every site that names a tapped element must exclude it, since a scope marker is not a thing the user touched.
