Browser measurement on the live page: with plausible-event-name=Buy only on the
<button type="submit">, clicking it sends Plausible's automatic "Form: Submission"
event and no "Buy". With the class on the enclosing <form> the click sends exactly
one {"n":"Buy"}. The button keeps its class as specified; the form now carries it as
well, so the Buy goal fires once per click.
Same behaviour measured on the live bootcamp page (its three CTAs also emit only
"Form: Submission") - left untouched, reported as a site-wide follow-up.
