/**
 * Builds a Morpho authorization `Requirement` that, once signed, lets `authorized` operate on
 * Morpho on the signer's behalf through `setAuthorizationWithSig` — the offchain-signature
 * alternative to a standalone `setAuthorization` transaction.
 *
 * The returned `Requirement.sign()` produces the EIP-712 signature over Morpho's `Authorization`
 * typed data, verifies it against the connected account, and returns a deep-frozen
 * `RequirementSignature` the bundler action helpers consume. Deadline defaults to two hours from
 * `Time.timestamp()`.
 *
 * @param viemClient - Connected viem `Client` whose `chain.id` matches `params.chainId`.
 * @param params - Authorization encoding parameters.
 * @param params.authorized - Account to authorize (GeneralAdapter1).
 * @param params.chainId - Target chain id.
 * @param params.nonce - The signer's current Morpho authorization nonce.
 * @param params.isAuthorized - Grant (`true`, default) or revoke (`false`).
 * @param params.deadline - Optional signature deadline in seconds.
 * @returns A `Requirement` whose `sign(client, userAddress)` produces the deep-frozen signature.
 * @throws {ChainIdMismatchError} when `viemClient.chain?.id !== params.chainId`.
 * @throws {MissingClientPropertyError} from `sign()` when the client has no `account.address`.
 * @throws {AddressMismatchError} from `sign()` when the client account differs from `userAddress`.
 * @throws {InvalidSignatureError} from `sign()` when EIP-712 verification fails.
 * @example
 * ```ts
 * import { createWalletClient, http } from "viem";
 * import { mainnet } from "viem/chains";
 * import { encodeBlueSignatureAuthorization } from "@morpho-org/morpho-sdk";
 *
 * const client = createWalletClient({ chain: mainnet, transport: http() });
 * const requirement = await encodeBlueSignatureAuthorization(client, {
 *   authorized: generalAdapter1,
 *   chainId: 1,
 *   nonce: 0n,
 * });
 * // requirement satisfies Requirement
 * ```
