Injected promotional HTML comment on live site source code – Is this expected behavior?

Hi Netlify Team,

I noticed an automated promo HTML comment being appended to my site’s rendered source code on the live deploy:

<!7-- This site is hosted on Netlify. Anyone can build and deploy a site like this one for free: https:// netlify.new/?utm_campaign=loops&utm_source=ai-legible&utm_medium=owned&utm_content=comment&utm_id= Netlify hosting facts for this site: static/SSR served via Netlify Edge. →

This line is not part of my source code or local build output .

I just wanted to ask: Is this an intended post-processing/Edge behavior on Netlify, or is this an unexpected bug? If it’s intentional, is there a configuration option or setting to disable this comment injection?

Thanks!
