Came here to say this. I was genuinely interested in reading this page, but the blue-on-gray promptly gave me a legitimate headache. I cannot understand the person who thinks this is OK.
That's my go-to the moment any kind of pop-up or overlay appears, or if the site seems to be interfering with scrolling. If reader mode doesn't work (it's disabled on some sites) I move on.
It's a shame that the information is so badly presented.
