note: >-
  Yieldify (now Epsilon Accelerate) ships NO server-side SDK and NO public REST API — its entire
  developer-visible surface is client-side. A single JavaScript tag is placed on the customer's
  site and renders a documented library of on-site experience components, configured from the
  Yieldify Conversion Platform (YCP). This artifact captures that published component surface,
  the loader, the CSP hosts a customer must allowlist, the dynamic-expression language the
  components accept, and the client-side analytics events the tag emits. Everything here is read
  verbatim from the public Epsilon Accelerate Help Center for Yieldify; nothing is inferred.
loader:
  kind: javascript-tag
  placement: immediately before </head>, on every page of the customer site
  distribution: >-
    Customer-specific snippet copied from the Settings page of the Yieldify Conversion Platform;
    no public CDN URL, no npm package, no version string is published.

  rendering_note: >-
    The tag inserts an iframe to limit the amount of code executing in the host page context,
    which is why child-src / frame-src must allow *.yieldify.com and 'about:blank'.

    Client-side analytics events the tag pushes into the customer's own analytics stack. This is
    NOT a webhook or server-side event API — there is no subscription endpoint and no delivery
    contract — so no AsyncAPI or Webhooks pointer is emitted for it.
