All-in-One chat button

One button, one panel, and your settings embedded in the snippet as inline JSON. Nothing is stored on a server and there is no widget key: the source product keeps its config remotely and counts views and clicks, while this builder runs in your tab and records nothing. Editing a shipped button means generating a fresh snippet and pasting it over the old one. The source's optional visitor PDF is not carried over; a file link would have to point at hosting of your own.
