  Cvent's client-side extensibility surface is Custom Widgets — developer-authored components that
  render inside Cvent-hosted event websites and registration flows, with a browser-side SDK for
  reading event objects and driving registration. This is distinct from the REST SDKs in packages/:
  a Custom Widget runs in Cvent's page, not in your server.

    description: >-
      A packaged widget with three required assets — an element (what renders), an editor (what the
      planner configures in Cvent's designer) and a configuration manifest — published into a Cvent
      account and then dropped onto event pages by non-developers.

    registry: none
    npm_package: null
    note: >-
      Cvent publishes no npm package for the widget SDK and no CDN loader URL in the public docs —
      the SDK is ambient inside the Cvent-hosted page. There is therefore no version to record and
      no way for a consumer to pin one. Recorded as an honest gap, not a missing check.
