{% comment %} `title` and `subtitle` are Bulma alternatives, not additive — `.subtitle` is
   defined after `.title` at equal specificity, so an element carrying both renders as a
   subtitle with the title rules dead underneath. The emphasis axis therefore carries the
   base class, and this branch is an `else` rather than an `elif` so exactly one of the two
   is always emitted: an `emphasis` that reached here empty would otherwise produce a
   heading with no Bulma class at all, which is a broken render rather than a missing
modifier. {% endcomment %}
