Much progress today:

• Pressing the red triangle while editing a content document now builds the site, and then opens it at the page built from the content you're working on.
• We now have handling for footnotes and transcribed poems.
• AR is more than half-way through converting the 1816 documents.
• I've cleaned up a lot of the errors in earlier conversions, and in the incoming files, which I've Tidied, transformed, and then been hacking away at in advance of her reaching them.
• The schema now does more in the way of useful constraint than before.
