{# alerts/_history_page.html — one page of alert episodes (#5316), then the
   sentinel that loads the next page as the reader nears it (core.paging,
   pref 172). An episode is one stretch out of quiet: what it reached, for how
   long, its worst reading, who was told; its transitions fold under it. #}
