  Selling a paid course: Paddle, a webhook, and the art of waiting

  A Student can now buy a paid Course. The interesting parts aren't the Buy button — they're the decisions underneath: the price you see is Paddle's, not ours (localized by IP); access is granted only by a signature-verified webhook, never by the browser saying "I paid"; and because that webhook is asynchronous, the panel shows a "Finalizing…" state that polls itself into "Continue Learning" with no refresh. Plus the idempotency that makes a double-delivered webhook a no-op.
