# Fragment parser - previously, we used lxml for fault-tolerant HTML5 parsing,
# but it blows up the size of the Docker image by 20 MB. We can't just use the
# built-in XML parser, as it doesn't handle HTML5 (because, yeah, it's not XML),
# so we use a streaming parser and construct the element ourselves.
