{# Logs (overseer_logs): one page's Logs section, or Overseer > Logs over
   every service (``logs_services`` to tick, ``logs_links`` for each line's
   page). The window's lines, newest first unless the order says otherwise,
   the filters that chose them, and new lines added over SSE at the newest
   end while it is open, unless paused (a paused line is dropped). Oldest
   first, the column-reverse scroller keeps that end in view as lines
   arrive. Above them, the window's volume (``logs.volume``): a bar per
   slice, stacked by tone, that narrows the lines to its time; a drag across
   bars narrows to all of them, and the bars behind the lines on screen
   are marked as the list scrolls (``data-range``, ``data-range-of`` in
   app.js). #}
