Comment (by mascguy):

 Reviewing what's done in other ports, I suppose we can handle this via
 direct use of `wget`/`curl`.

 The following is semi-complete, apart from copying the artifacts to the
 appropriate location(s) in the work area. (It's slightly more involved
 than would otherwise be required, due to multiple artifacts named
 `variables.css`.)

 {{{
     depends_fetch-append \
                     path:bin/wget:wget

     post-fetch {
         # Explicitly fetch CSS artifacts; all of this must remain in-sync
 with project build script
         set notebook_css_ver            5.4.0
         set jupyterlab_css_ver          3.1.11
         set jupyterlab_theme_light_ver  3.1.11
         set jupyterlab_theme_dark_ver   3.1.11

         set notebook_css_url \
 https://cdn.jupyter.org/notebook/${notebook_css_ver}/style/style.min.css
         set jupyterlab_css_url \
             https://unpkg.com/@jupyterlab/nbconvert-
 css@${jupyterlab_css_ver}/style/index.css
         set jupyterlab_theme_light_url \
             https://unpkg.com/@jupyterlab/theme-light-
 extension@${jupyterlab_theme_light_ver}/style/variables.css
         set jupyterlab_theme_dark_url \
             https://unpkg.com/@jupyterlab/theme-dark-
 extension@${jupyterlab_theme_dark_ver}/style/variables.css

         set css_fetch_dir \
             ${distpath}/css
         set wget_fetch_cmd \
             "${prefix}/bin/wget --no-verbose --no-check-certificate
 --timestamping"

         xinstall -d \
             ${css_fetch_dir}/notebook_css \
             ${css_fetch_dir}/jupyterlab_css \
             ${css_fetch_dir}/jupyterlab_theme_light \
             ${css_fetch_dir}/jupyterlab_theme_dark

         system -W ${css_fetch_dir}/notebook_css \
             "${wget_fetch_cmd} ${notebook_css_url}"
         system -W ${css_fetch_dir}/jupyterlab_css \
             "${wget_fetch_cmd} ${jupyterlab_css_url}"
         system -W ${css_fetch_dir}/jupyterlab_theme_light \
             "${wget_fetch_cmd} ${jupyterlab_theme_light_url}"
         system -W ${css_fetch_dir}/jupyterlab_theme_dark \
             "${wget_fetch_cmd} ${jupyterlab_theme_dark_url}"
     }
 }}}

 I'll leave this out here for a day or two, in case folks have any
 suggestions to improve/streamline the approach.

 And ultimately we should reach out to upstream, to see if they can
 eliminate the need for all of this long-term.
