Payment Dialog

The in-app payment sheet for a transactional charge: a known amount due now (an outstanding balance, a late-cancel fee). Built on the same picker as /checkout (shared payment-fields). Two things checkout doesn’t have: a card on file (the default; Use a different card reveals the same fields), and a result step, where the charge resolves onto a success or error screen, not a snackbar. Click to open; the demo charge succeeds unless noted.
