+ * The widget bundle (/ask/widget.js) and its API (/ask/api/ask) are served by

+ * production on davidawindham.com and locally on daw.stu (see the vhost
+ * ProxyPass directives). Same-origin means no CORS to worry about.

+ * We probe the widget URL first and only inject it if the response is really

+ * returns HTML, and injecting that would throw. The probe makes it a silent
+ * no-op until the backend is actually serving the widget. The widget sets
+ * window.__dawaskLoaded to guard against a double instance.
