/**
 * Signs a transaction.
 *
 * - Docs: https://viem.sh/docs/actions/wallet/signTransaction
 * - JSON-RPC Methods:
 *   - JSON-RPC Accounts: [`eth_signTransaction`](https://ethereum.github.io/execution-apis/api-documentation/)
 *   - Local Accounts: Signs locally. No JSON-RPC request.
 *
 * @param args - {@link SignTransactionParameters}
 * @returns The signed serialized transaction. {@link SignTransactionReturnType}
 *
 * @example
 * import { createWalletClient, custom } from 'viem'
 * import { mainnet } from 'viem/chains'
 * import { signTransaction } from 'viem/actions'
 *
 * const client = createWalletClient({
 *   chain: mainnet,
 *   transport: custom(window.ethereum),
 * })
 * const signature = await signTransaction(client, {
 *   account: '0xA0Cf798816D4b9b9866b5330EEa46a18382f251e',
 *   to: '0x0000000000000000000000000000000000000000',
 *   value: 1n,
 * })
 *
 * @example
 * // Account Hoisting
 * import { createWalletClient, http } from 'viem'
 * import { privateKeyToAccount } from 'viem/accounts'
 * import { mainnet } from 'viem/chains'
 * import { signTransaction } from 'viem/actions'
