-  The only differences between this copy and the original are that we've dropped:
-
-  - The `{{ if hasPrefix . "G-"}}` condition
-  - The `{{ else }}` block
-  - The `anonymize_ip` argument to the `gtag()` call, since it is superfluous.
-    For details, see https://github.com/gohugoio/hugo/issues/10093.
