NOTE(s):
* [20230510: Using https://pypi.org/project/furo wheel to build docs w/o switching 'furo' => 'alabaster'.; not passible anymore as it's difficult to directly install a wheel at build time]
* [20230507: furo isn't installable since it doesn't support python-sphinx >= 7.0]
* [20230522: furo supports python-sphinx >= 7.0 now]

(a static, non-nodeenv python-sphinx-theme-builder &) python-furo isn't available, need to adjust kitty-<version>.tar.gz:
kitty-0.x.y/docs/conf.py:html_theme = 'furo'
kitty-0.x.y/docs/conf.py:html_theme = 'alabaster'
