{#- An SVG diagram from a file next to the post, inlined so it follows the page's colours and dark mode:
    {{ diagram(src="architecture.svg", caption="…", min_width=580) }}
    min_width: narrower than this, the diagram scrolls sideways instead of shrinking. It is a class (mw-580,
    in devlog.css), because the site's Content-Security-Policy refuses style attributes. The SVGs carry no
    <style> block either: their rules are in devlog-diagrams.css. -#}
<figure class="arch">
  <div class="canvas{% if min_width %} mw-{{ min_width }}{% endif %}">
{{ load_data(path=page.colocated_path ~ src, format="plain") | safe }}
  </div>
  {%- if caption %}
  <figcaption>{{ caption | markdown(inline=true) | safe }}</figcaption>
  {%- endif %}
