Nested navigables were represented through compositor surface ids owned by the parent context. That forced CompositorState and ContextState to maintain bidirectional attach/detach bookkeeping, publish child snapshots into a surface map, and keep presentation mode variants just to distinguish UI presentation from parent composition. Record the child compositor context id directly in the display list and let the compositor resolve it against the painting parent at playback time. Child contexts now keep their parent context id and latest rendered surface, while parents no longer track child maps or compositor surface ids. UI presentation is represented separately from parent composition, so closing a page only stops client presentation and nested contexts keep using set_parent_context.
