{% comment %} MD3 checkbox row: 18dp rounded-square control (styled in forms/fields.css) with body-large label and optional supporting text under it, list-item style — no pill container. Errors render as MD3 supporting text below the row. Django's own widget draws the box, so it carries what the form declares; the help text and errors take Django's ids, which the box's aria-describedby points at. {% endcomment %} {% load phoxtail_core_tags %}
