Here's a place where <code>header</code> might be an appropriate element (since they took away <code>hgroup</code> that was made for exactly this use case). This shouldn't be wrapped in a section, but could be the header for an article, containing two headings.

<pre><code><article>
  <header>
    <h2>{{ _('Gigabit Community Fund') }}</h2>
    <h3>{{ _('Learn on tomorrow’s networks') }}</h3>
  </header>
</code></pre>
