This is what I am getting. It really wants to style the Paragraph output like it’s an entity reference, since under the hood it literally is.
<!-- BEGIN OUTPUT from 'themes/contrib/at_theme/at_core/templates/field/field.html.twig' -->

This is what I want (taking the debug stuff out for brevity). Basically I think I should be able to interpolate the value of the typed-identifier-type field (ISBN) into the class name on data-quickedit-entity-id="paragraph/4", so that the actual structure/meaning of the data is in the structure of the HTML:
<div data-quickedit-field-id="node/17/field_typed_identifier/en/full" class="field field-node--field-typed-identifier"><h3 class="field__label">Identifier</h3><div class="field__items"><div class="field__item">
<div data-quickedit-entity-id="paragraph/4" class="paragraph--typed-identifier paragraph--typed-identifier-type--ISBN">
<span class="paragraph--typed-identifier-type">ISBN</span>: <span class="paragraph--typed-identifier-value">978123456789X</span>
</div>
</div></div>
</div>
