Does underarmour.com allow AI crawlers?

What is underarmour.com built with?
The homepage exposes these fingerprints: Next.js. A site behind a CDN or rendered server-side may use more than it reveals.
Where does this data come from?

Is any of this traffic or authority data?
No. Traffic, authority and ranking figures cannot be measured by inspecting a domain, only modelled. Everything here is a direct observation.
I own underarmour.com and want this page removed.
Ask through the contact page on this site, from an address at the domain, and the report will be taken down. It only ever shows what the domain already serves publicly.
