Checkout safety
Three modes. Staging runs the whole flow on a preview you own and may type the Stripe test card 4242 4242 4242 4242. Production stops when Stripe Checkout or your payment page is on screen and checks the price. Post-payment skips the card form and uses a restricted read key to look at recent payment events and pending webhooks. Any other card number is rejected before it is typed. The browser identifies itself as FunnelWatchBot.
