<bolt-figure> to wrap your figure media and caption. The figure media must have the attribute slot="media" or be wrapped by an element with that attribute. Everything else inside the <bolt-figure> tag is considered the caption. We recommend simply using text with optional inline markup (as seen below).
<bolt-figure>
<bolt-image src="/images/placeholders/landscape-16x9-mountains.jpg" slot="media"></bolt-image>
This is a caption. Lorem ipsum <em>dolor sit amet</em>, consectetur adipiscing elit <a href="#">text link</a>.
</bolt-figure>
