  DeBounce ships client-side and embedded surfaces that are distinct from server
  SDKs: a drop-in browser widget that attaches real-time validation to any form,
  and two host-application integrations (WordPress, Google Sheets) that wrap the
  same API for non-developers. These are the low-code path onto the API and they
  are what most DeBounce customers actually deploy.

families:
- family: browser-widget
  name: Real-Time JavaScript Validation Widget
  description: >-
    A single script tag pasted before the closing </body> tag. Once loaded the
    widget auto-detects email fields on the page and validates on type or blur,
    checking formatting, disposable domains, mailbox existence and typo domains
    before the form can submit. No backend work is required.
  loader:
    tag: <script src="https://cdn.debounce.io/widget.js"></script>

      key's approved CORS domain list.

      The documented loader answered 200 with an EMPTY body and an image/jpeg
      content-type at probe time, with and without a browser User-Agent and a
      debounce.com Referer. Recorded exactly as observed; not asserted as broken
      for all callers, but a consumer cannot verify the asset from the documented
      URL either. The distribution is also unpinned — see
      packages/debounce-packages.yml.
