 * The ECDSA-P256-relevant subset of the p256 WASM exports.
 *
 * The p256 module hosts the full elliptic-curve substrate (field,
 * scalar, point, RFC 6979 K derivation, embedded SHA-256 + HMAC) and
 * the four high-level ECDSA entry points (keygen, sign, signInternalPk,
 * verify). The wrapper additionally drives `pointDecompress` + `feToBytes`
 * for the SEC 1 §2.3.4 uncompressed-pk emission path; those two
 * substrate exports are public because no high-level ABI covers
 * "given a compressed pk, return its uncompressed form" without
 * round-tripping through verify. Substrate test hooks live outside
 * the consumer-facing ABI.
