Why: Project document and knowledge structures can contain nested nodes whose children must remain navigable beyond the first section level. Evidence: A RED test first showed child-bearing sections were not expandable; presentation and design-guard tests, knip baseline 43, and npm run build now pass. Impact: Recursively render any node marked with children while preserving current document fallback and readable node states. Refs: TT-N01, TT-N02, TT-D01, TT-U01; two trees one graph vertical slice
