The font-family list in the stylesheet is both too long and weirdly specific, yet incomplete. I don't have any of these very specific Windows, Apple, or Android fonts installed on my machine, so it picks the first one it can find which is "Noto Color Emoji" and uses that as the main font. The end result that all the space characters are about two miles wide, and the rest is rendered using the browser default "sans-serif". You list 13 different sans-serif fonts, and two emoji fonts. The browser is perfectly capable of picking its own Emoji font for emoji characters so this is all completely unnecessary. Please just use "font-family: sans-serif" if that's what you want, otherwise use web fonts. There's no need for this level of complicated font family micro-management, that doesn't even work.
