{#-
  Visits from the maintainers are tagged so that the Internal Traffic data
  filter in Google Analytics can drop them. These docs share the
  cpp-linter.github.io origin with the organization site, which sets the flag:
  opening any page there or here with ?internal=1 stores it in localStorage and
  ?internal=0 removes it. While it is there, every event carries
  traffic_type=internal. It runs before the theme's own snippet, so the setting
  is queued ahead of the first page_view.
