{# plugins/prometheus/templates/prometheus/target.html — one scrape target
   (milestone 506): what its newest scrape found, then every series it
   stored, grouped by metric, each with its labels and newest value and a
   link to its chart. A state set reads as one row per thing it describes,
   naming the current state (#5689). #}
