+     Posts straight to Plausible's Events API instead of loading the official tracking
+     script: that script hard-blocks localhost/private-IP hostnames client-side (to stop
+     developers polluting their own stats while building a site), but a huge share of
+     self-hosted installs are opened via exactly that - http://localhost:port or a bare
+     LAN IP - on the very machine running the panel. The Events API itself has no such
+     restriction (confirmed directly against telemetry.xenne.eu), so calling it ourselves
+     is the only way to actually count those installs. -->
