+    // In other languages, for example, German (subdomain `de`), 20px is too big so the text is wrapped and breaks the UI. 19px is enough to fit the text on one line on the German site.

+    // There's probably a smarter way to do it, but probably also more complex. This change in font should be acceptable and we can revisit it every time there's a longer text.
