Fun fact: fetching [favicons](https://en.wikipedia.org/wiki/Favicon) from
various domains is a dark art. Might seem trivial at first, but it's very
complicated. A simple request for a `favicon.ico` will net strange returns ---
like serving a text file as a `favicon.ico`.

Better to leverage a browser which excels at interpreting favicons or contact a
{{< abbr CDN "Content Delivery Network" >}} of a major search engine. Make sure
to cache the results.
