Test mode

Exercise the full payment flow without moving real crypto.

Use a pk_test_ key (or create a test invoice from the dashboard).

Checkout shows a Test mode banner.
Deposit addresses are not real — do not send mainnet crypto to them.
Use Simulate a successful payment on the hosted page to drive the same confirmation / webhook path as a real payment.
Card onramp in test mode uses Stripe test cards when configured.

When you're ready, switch to a pk_live_ key. Live invoices get real addresses.
