Managing _cfuvid with a consent banner

A consent banner lists _cfuvid in its cookie table under Essential, the category that is always active. Because it is strictly necessary, it works without an opt-in, and listing it keeps your cookie policy accurate. Kukie.io's cookie scanner finds it when it scans your website.
