{# docker/service.html — one swarm service (#5302, #5310): a header that says
   whether it is well and what it runs; its last failure only while it is in
   trouble; its CPU and memory over time; one table of its tasks, the running
   ones first with what they use; and the logs of every task it has run.
   A failure's "Logs →" lands on #logs with ?task= picked. #}
