This search result page is blank, at least on latest Firefox for me:
https://kagi.com/search?q=%22%40import%22
While a minor issue from a user perspective, I raise it in case it's a problem with input not being properly escaped somewhere, as that could have nasty implications if there's a way to exploit it with other queries.

The search should proceed as normal and show results where the string "@import" appears verbatim.
