### IMPORTANT!
# we can not use the usual lambda/python image because there's no sane way to
# install the version of pango we need for weasyprint
#
# huge thanks to this page for the solution used here:
# - https://www.slim.ai/blog/containerized-lambda-in-python-language/
# notes about pango and weasyprint:
# - https://github.com/kotify/cloud-print-utils/pull/7/files
# - https://github.com/Kozea/WeasyPrint/issues/1384#issuecomment-902620644
