Closing, please see original Issue as to why. You did good work, this was just a mistake on my part:

• https://github.com/creativecommons/search/issues/279#issuecomment-2402946720

Apologies, I misread this. The span here has a purpose, which is to allow a placeable spot for the "skip to content" link to target within the markup. As spans are semantically meaningless it can be present and empty while serving this function. Its function here is a requirement for adequate Accessibility.

Now that I've revisited it, this should have been closed. Thanks for understanding, sorry for the confusion.
