WordPress runs jQuery in noConflict mode, so bare $ is undefined. The
clipboard module called $(this) on every click and $.isFunction on the
copy result, so any click on a [data-clipboard-text] button threw
"$ is not a function" and copied nothing.
This was latent: the only prior emitter was the paid card, and the click
path only ran when a user actually clicked it. Exposing the copy button on
the download box made it reachable on every resource, surfacing the error.
Bind through jQuery explicitly, guard notyf so a missing toast lib cannot
also throw, and drop the _win.bd dependency (that payload only gains .bd
once main.js runs). Contract-lock the module under simulated noConflict.
