+In some cases, a third-party script can collect browsing interest information about users
+using new experimental functionality called Topics API. The first script in the page header
+will alert you if a script is attempting to do this. The line can be removed if your site
+is turning off Topics API with a Permissions-Policy, running without third-party scripts,
+or if you are using Topics API.
+
+The line can be changed to send an analytics event to check if third-party scripts begin trying
+to use Topics API in production.
