1//! CMP20 scheme registration.
2//!
3//! Two logical operations — DKG and signing — exposed as two scheme
4//! names so the framework's single-name/single-kind `TcScheme` trait
5//! can route each.
6//!
7//! | Name                    | Kind        | Produces                          |
8//! |------------------------|-------------|-----------------------------------|
9//! | `CMP20-ECDSA-P256`       | `Dkg`       | per-party `Cmp20Share` + pubkey    |
10//! | `CMP20-ECDSA-P256-SIGN`  | `Signature` | 64-byte `(r, s)` ECDSA signature  |
