## Notes

Diagram-rendering JS library, injected into built slide HTML by the `inject_mermaid` step of `build-slides.sh`. Each `<pre><code class="language-mermaid">…</code></pre>` block emitted by [marp](marp.md) is rewritten into `<div class="mermaid">`, then `mermaid.run()` renders it client-side on page load.
