Got the last set of changes from JS-R, and implemented them. One area that needs improvement, but will have to wait now, is the linking of tables to their detailed explanations on another page. Those links are straight links, but could instead be hide/show functions that reveal the explanations, imported into the table page itself by PHP from the source document (which is also independently readable on the site). That would be more elegant, but it's not a two-minute job.
