      # Mount the host's "io" directory within the container, so that the host can "see" files uploaded via the web UI.

      # ...but, don't mount the following subdirectories. For these subdirectories, we want the container to be
      # initialized with the subdirectories as they exist in the container image, instead of as they exist on the host.
      # That way (a) the installed npm packages are consistent with the container's architecture (i.e. amd64 vs. arm64);
      # and (b) the built client already exists and is ready to be served. See https://stackoverflow.com/a/62799209
      # for an explanation of this "anonymous volume" technique.
