+-- One row per distinct work, shared by every bookmark that tracks it

+-- into. title/series_url/cover are written once, at creation, and never
+-- again: client-supplied values are ignored once the row exists and the
+-- poller is the only party that may change them. kind and the latest-chapter
+-- fields are last-write-wins like the bookmark's own fields.
