Always h1.h3, so pages cannot drift apart. Heading rank is structural; size is
fixed. Never pick a heading level for its size.

    {% trans "Widgets" as parent %}{% url 'public:widget-list' as parent_url %}
    {% include "yksa/ui/_page_title.html" with title=widget.name parent=parent parent_url=parent_url %}

A page one level deeper names its grandparent too, so the trail reaches the
section root rather than starting halfway down it:

    {% include "yksa/ui/_page_title.html" with title=_("Status") parent=widget.name parent_url=... grandparent=_("Widgets") grandparent_url=... %}

Put it inside the page header's flex row; the row owns the actions on the right.
