How not to trigger site analytics from localhost

That being, I accidentally had my analytics platform (with session recordings) enabled on a local website I was developing.

Then, I realized, I had session recordings of the entire history of the website. I could see and rewatch the development progress as a timelapse, pretty cool: https://x.com/XCSme/status/1878269904698163613

I wrote my site in pure html/css/javascript website, and along the way found that I was unintentionally triggering my site analytics every time I started the site from localhost. A short couple of searches later and I had this rather simple solution.
