Gateway 3DS test cards
Per-PAN test cards that drive 3DS challenge, frictionless, and bypass flows in
each gateway's test mode. Cross-referenced from 3ds-flows.md. For
single-gateway work, prefer the gateway skills (stripe-test-cards-and-webhooks,
payment-gateway-sandboxes).

| 4000 0025 0000 3155 | Authentication required (challenge), payment failure after success |
| 4000 0000 0000 3220 | Authentication required (challenge), payment success |
| 4000 0000 0000 3055 | 3DS supported but not required (frictionless) |
