The problem is more specific.  Put this in a file an open with
eww-open-file, and eww won't be able to display it:

<img 
src="https://cdn.christine.website/file/christine-static/stickers/mara/hmm.png"; 
alt="Mara is hmm">

And the reason is that the web server responds to the fetch with an 401
Unauthorized.  So the CDN is just denying the requests.  I.e., it's a
server issue, not an Emacs issue.

(I don't know why it's doing this, though -- it's probably using AI to
determine if the request is "legitimate" or not, and some combination of
headers we're sending is tripping it.)

Ah!  It's Cloudflare:

CF-Cache-Status: BYPASS
Expect-CT: max-age=604800, 
report-uri="https://report-uri.cloudflare.com/cdn-cgi/beacon/expect-ct";

They have a lot of issues like this.
