Connections are keyed by credentials mode. The crossorigin attribute
opened the imgs.blue socket in anonymous-CORS mode, but every request
to that origin is a plain <img src> avatar fetch (BlobCDNURL /
resizeImage) in no-cors mode, so nothing could reuse it. The browser
opened a second connection anyway and Lighthouse flagged the hint as
unused while still listing imgs.blue as a preconnect candidate worth
~300ms of LCP.
The attribute is correct for the font preloads below, which is where it
was likely copied from; comment the distinction so it stays put.
