Unfortunately we cannot support Mermaid diagrams in plone-sphinx-theme. See:

• 0.9.2: pep517 based build fails mgaitan/sphinxcontrib-mermaid#137
• Looking for maintainers for sphinxcontrib-mermaid mgaitan/sphinxcontrib-mermaid#148

I would love to support mermaid, but until that issue is resolved, I can't merge this PR. We can keep it open until then.

Yay.

@jensens let's revisit this. See #1777.

@jensens I went ahead and did a review by directly editing the file. I approve. Is this ready to merge? It's marked as Draft.

@jensens I made a couple of enhancements to the Mermaid diagrams. Now they have alt, caption, and zoom attributes.

I don't understand the second diagram, but it's pretty.

@jensens would you please take a look at the pull request preview at https://plone6--1715.org.readthedocs.build/conceptual-guides/package-dependencies.html and let me know if this is ready to merge or you want to make any changes? I moved it into the Conceptual Guides from contributing to Plone core, since this is not really a how-to guide. Thank you!
