The architecture image was drawn on https://www.draw.io/. The native draw.io source file is called architecture.xml, while architecture.svg is its SVG export.

To change the architecture diagram, go to https://www.draw.io/ and import the XML source file. After making changes to the diagram, export the result as SVG. Update both the source file and the SVG export in this directory.
