  The dashboard's own OTP application. Starts a private `Phoenix.PubSub` (so the
  dashboard never has to share the host's) and the telemetry `Collector` that
  folds the `[:bloccs, …]` stream into per-network rolling windows.

  Auto-starts on boot. Opt out (e.g. to supervise it yourself) with:

      config :bloccs_web, auto_start: false
