Nice blog design, inspired by the Tufte Jekyll theme
https://github.com/kmayer/tufte-jekyll
which in turn is based on
https://github.com/edwardtufte/tufte-css which is demonstrated on https://edwardtufte.github.io/tufte-css/
The latter uses CSS, so it should be possible to use it with org-mode.

Later, I rediscovered the blog via Sacha Chua's link https://takeonrules.com/2024/05/18/a-quiet-morning-of-practice-to-address-an-observed-personal-computering-workflow-snag/ on https://sachachua.com/blog/2024/05/2024-05-20-emacs-news/
