I installed a #quicklook #markdown plugin a friend recommended and saw a dependency for something called `duti` which is a CLI tool for assigning default handlers for files and urls. I usually use the 'Swift Default Apps' preference pane for this which superseded an older take but somehow duti escaped my notice and this repo has been here for like over a decade so welcome to the past.

#duti: https://github.com/moretension/duti/

the quicklook plugin install: `brew install --cask xykong/tap/flux-markdown`
