Canonical JSON + hash

// click "Build pack"

Note on signing

In production, the canonical JSON is signed with an Ed25519 key (see Admin » Keys for KID rotation). We display the signature field as a placeholder so the shape is realistic; the bytes are not a real signature because no private key is available client-side. The hash is computed in your browser via SubtleCrypto and is real.
