It is well known that text that is too thin and too light-colored is not great to read. The text modification shown here makes certain letters easier to read, but it appears this is partially because the rest of the text is specifically difficult to read. The background of the page very light grey, it looks like, which would magnify this effect even more.

I wonder what this would look like with a not-too-thin-font that is black or near-black. I also wonder what it looks like on a full-width paragraph, as the sibling commenter mentioned.

Regardless, it's always nice to see innovation in this space!
