note: 'ClickFunnels ships a browser SDK that turns a page you host yourself into a ClickFunnels funnel step:
  it tracks visits, captures opt-ins, carries contact identity across steps, and mounts real gateway payment
  UI. The markup contract is attribute-driven (data-cf-element) rather than a custom-element library.'

- family: ClickFunnels SDK loader
  type: script
  loader: https://sdk.myclickfunnels.com/sdk.js
  embed: <script src="https://sdk.myclickfunnels.com/sdk.js" defer></script>
  pairing: A cf-page-token meta tag binds the page to a registered external page.
  note: sdk.js is a small loader that injects the real bundle from the same host; the distribution is unpinned.
