Using `layout` to arrange things other than figures is possible but currently examples are buried in [Guide > Authoring > Figures](https://quarto.org/docs/authoring/figures.html#block-layout) and [Guide > Interactivity > Component Layout](https://quarto.org/docs/interactive/layout.html#panel-layout). Perhaps it should be discussed as part of [Guide > Authoring > Article Layout](https://quarto.org/docs/authoring/article-layout.html)
