{# Intro info-box partial. Pages set ``caller()`` body via
   ``{% call render() %}<copy here>{% endcall %}`` -- the partial
   wraps it in the standard ``alert alert-info`` styling so all
   per-page intros render identically.

   Used by every operator-facing /ui page that needs a one-
   paragraph section description below the navbars and above the
   content. Consolidates 5+ copies of the same DOM shape.
