I am a partially vision-impaired man, and I really can't stand the dark-grey on light-grey texts that a lot of modern web pages have. They are essentially unreadable to me. In order to comfortably read this article, I had to go to Firefox's Style Editor and make the text actually black.

And it is ironic that an article about text rendering uses such low-contrast and small-sized text.

Background is white and the text is #333. Contrast ratio is 12.63:1, which isn’t bad at all.

Can’t really fault the author here

Does the Reader View in Firefox help here?

Completely forgot about it. Yes, it does improve readability for me.

I mainly prioritize making my pages work reasonably with different zooms and window sizes, since all I really know for certain is that there's no ideal for everyone.

The font settings are just from a copy of bootstrap from like 6 years ago, because I have absolutely no eye for this sort of thing.
