Apparently, even though marked (the markdown parser) skips the <style> block where I set the logo CSS, the inline URL linkifier turns the background-image: url(...) into a link

background-image: url(<a href="...">...</a>);

which obviously doesn't work.

The remedy is to include the styles and scripts inside a bare <div> and to make sure there is no leading whitespace on CSS lines inside the <style> tag.
