What the toggles do

  • Consent Management Platform — Big Crunch's CMP. Turn off if you run a different one.
  • Prebid — preloads the per-property Prebid bundle. Turn off if your property doesn't run header bidding.

Content Security Policy

Lighthouse and the CMP inject their stylesheets at runtime, so a strict CSP must allow style-src 'unsafe-inline' (or a nonce) for our origin.

Queueing commands before the bundle loads

To push commands onto BCLighthouseTag.cmd before main.js finishes loading, declare the queue first:

<script>
  window.BCLighthouseTag = window.BCLighthouseTag || { cmd: [] };
  BCLighthouseTag.cmd.push(function () {
    /* runs once main.js is ready */
  });
</script>
