 ### Draw.io source diagrams
 
-When a page needs a Draw.io diagram, keep the editable `.drawio` XML in the documentation repository and render that source directly with `docusaurus-plugin-drawio`. Load `drawio-main` to author or change the diagram, then follow [references/drawio-source-diagrams.md](references/drawio-source-diagrams.md) to install the plugin with pnpm, register it, consume the source from MDX with `@theme/Drawio` and `!!raw-loader!`, select multi-page diagrams, and verify the production build and browser rendering. An exported PNG/SVG alone is not an onboarded source diagram.
