  Goodays ships a client-side Web SDK plus a family of embeddable widgets that
  merchants drop into their websites, mobile apps, kiosks and WiFi portals to
  collect and display customer feedback. Loaded from cdn.goodays.co and exposed
  through the global `cz` namespace; declarative widgets are wired via <a> tags
  with the class `goodays-widget` and data attributes, or launched imperatively.
