I love how much utility 60+ year old Unix commands have. Very powerful, requiring only a few kB of ram, and even 20+ years later, I’m still discovering new utilities.

I did something similar for https://isgithubipv6.web.app/ . Most static site generators are huge ( I was aiming for < 5mb docker container) . I went with `envsubst` , env vars and a simple HTML template.
