Blocked scripts (these only run after consent)
<script type="text/plain" data-consent="analytics"
        src="https://www.googletagmanager.com/gtag/js?id=G-DEMO"></script>

<script type="text/plain" data-consent="advertising">
  console.log("Meta Pixel would fire now — user opted into advertising.");
</script>
The page below contains these inert tags. They become real scripts only when the matching category is accepted. Watch the console.
