GET/v1/preview

The design's picture (image/jpeg) for a cart line.

What it does

The picture of a design for your cart line, to whoever holds design + sig: the same pair the designer gave your page. No key. Cached privately for 60 seconds (Cache-Control: private, max-age=60), because the picture changes with the design. One plain-text 404 for every refusal, so ids cannot be probed.

No key: the design + sig is the credential.
