Managing _cltk with a Consent Banner

A consent management platform keeps _cltk blocked until the visitor opts in to the analytics category. Kukie.io's scanner detects it automatically, categorises it, and the banner's auto-blocking holds back the script that sets it until consent is given - visitors who decline never receive it.
