Article hatnotes should render approximately as they appear on mobile web. Some examples:
- https://en.m.wikipedia.org/wiki/Wordless_novel
- http://marvin.wmflabs.org/wiki/Christine_Lavin
- http://marvin.wmflabs.org/wiki/Wikipedia:Hatnote (note: this is not part of the main namespace and there are numerous rendering issues so focus only on the hatnotes)
