I always use the links terminal browser test. If the site is usable in my terminal with the `links https://usabilitypost.com/2012/11/05/stop-fixing-font-smooth...` command then it is well done. Chances are, if you are using any type of special font rendering to fix a UI issue you are also doing other things on that page that will cause it to not display properly in links. Also, shout out to the author for having their article actually render well in links!
