Issue: renderedDocument is cached after the first render. If new elements are added later, renderDocument() still returns the old cached value because renderedDocument is no longer empty.

string renderDocument() {
    if (renderedDocument.empty()) {
        renderedDocument = document->render();
    }
    return renderedDocument;
}

Fix: Clear the cache (or mark it dirty) whenever the document is modified so the next call re-renders the updated document.
