I seem to have recovered from my tragically stupid mistake that led to the loss of all the content for this site.
All the pages were recoverable. Some of the tags are probably different (perhaps some are even better, who knows?). I should probably ditch the tags anyway. I’ve undoubtedly lost some post-hoc edits and addenda. But, for what it’s worth, all the pages are restored.
New backup systems (three!) are in place and currently being tested. Time to move forward!
