/**
* WHAT IS THIS FILE?
*
* What happens when someone deletes the plugin — not deactivates it, deletes it.
*
* WHY IS IT A SEPARATE FILE?
*
* WordPress runs this file on its own, without loading the rest of the plugin. That
* is why it repeats a couple of table names instead of calling our own classes:
* nothing else is loaded, so there is nothing to call.
*
* WHAT IT DOES AND DOES NOT DELETE
*
* DELETED: our two tables, our settings, the activity log. Those are ours, they are
* meaningless without the plugin, and leaving them behind is the kind of litter that
* accumulates in a network's database for years.
*
* NOT DELETED: the converted document pages. Those are real published content with
* real URLs that people have bookmarked, shared, and linked to. Deleting a thousand
* live pages because someone removed a plugin would be a shock, not a cleanup — and
* it is not recoverable. They become ordinary orphaned posts of an unregistered post
* type: invisible, harmless, and still there if the plugin comes back.
*
* Nor are the original PDFs touched, obviously. We never owned those.
