Update: I see now that the culprit is …/layouts/_markup/render-image.html in a theme I am using. And I suppose that then the response will be to ask about this on the HugoBlox discord server. But even so, if anyone has suggestion or advice here, I would appreciate that.
In my markdown source, I have something like.
Sections marked with the 
are not intended for you and might just muddy the waters.
I want to image to be inline, as I would expect with typical markdown to HTML processing, but it is getting wrapped in a figure,
ections marked with the
<figure>
<div class="d-flex justify-content-center">
<div class=w-100>
<img src=/images/dangerous-bend.svg
alt="dangerous bend symbol"
loading=lazy data-zoomable>
</div>
</div>
</figure>
are not intended for you and might just muddy the waters.</p>
which is what I would expect if I had used the `figure` shortcode, but I did not want want a figure here.
Note I am using the HugoBlox Academic CV theme. But I would like help in understanding what I should look for in what is triggering the use of the figure template and I can avoid that trigger. Alternatively, if there is some other, recommended way, to inline an image in the text.
I have looked at other related discussions, but I have found the answers unhelpful. To whatever extent this is a markdown and CSS issue, it is Hugo that has decided to treat that as a figure.
