 * clashes when switching implementations.
 *
 * 2. Ownership can be transferred via `transferOwnership`, similar to the
 * behavior of an `Ownable` contract. This is a simple single-step operation,

 * validation for both validating the signature on user operations and in
 * exposing its own `isValidSignature` method. This only works when the owner of
 * `LightAccount` also support ERC-1271.
 *
 * ERC-4337's bundler validation rules limit the types of contracts that can be
 * used as owners to validate user operation signatures. For example, the
 * contract's `isValidSignature` function may not use any forbidden opcodes
 * such as `TIMESTAMP` or `NUMBER`, and the contract may not be an ERC-1967
 * proxy as it accesses a constant implementation slot not associated with
 * the account, violating storage access rules. This also means that the
 * owner of a `LightAccount` may not be another `LightAccount` if you want to
 * send user operations through a bundler.

/**
 * @dev Identical to OpenZeppelin's `Initializable`, except that its state variables are kept at a custom storage slot
 * instead of at the start of storage.
 *
 * This is a base contract to aid in writing upgradeable contracts, or any kind of contract that will be deployed
 * behind a proxy. Since proxied contracts do not make use of a constructor, it's common to move constructor logic to an
 * external initializer function, usually called `initialize`. It then becomes necessary to protect this initializer
 * function so it can only be called once. The {initializer} modifier provided by this contract will have this effect.
 *
 * The initialization functions use a version number. Once a version number is used, it is consumed and cannot be
 * reused. This mechanism prevents re-execution of each "step" but allows the creation of new initialization steps in
 * case an upgrade adds a module that needs to be initialized.
 *
 * For example:
 *
 * [.hljs-theme-light.nopadding]
 * ```solidity
 * contract MyToken is ERC20Upgradeable {
 *     function initialize() initializer public {
 *         __ERC20_init("MyToken", "MTK");
 *     }
 * }
 *
 * contract MyTokenV2 is MyToken, ERC20PermitUpgradeable {
 *     function initializeV2() reinitializer(2) public {
 *         __ERC20Permit_init("MyToken");
 *     }
 * }
 * ```
 *
 * TIP: To avoid leaving the proxy in an uninitialized state, the initializer function should be called as early as
 * possible by providing the encoded function call as the `_data` argument to {ERC1967Proxy-constructor}.
 *
 * CAUTION: When used with inheritance, manual care must be taken to not invoke a parent initializer twice, or to ensure
 * that all initializers are idempotent. This is not verified automatically as constructors are by Solidity.
 *
 * [CAUTION]
 * ====
 * Avoid leaving a contract uninitialized.
 *
 * An uninitialized contract can be taken over by an attacker. This applies to both a proxy and its implementation
 * contract, which may impact the proxy. To prevent the implementation contract from being used, you should invoke
 * the {_disableInitializers} function in the constructor to automatically lock it when it is deployed:
 *
 * [.hljs-theme-light.nopadding]
 * ```
 * /// @custom:oz-upgrades-unsafe-allow constructor
 * constructor() {
 *     _disableInitializers();
 * }
 * ```
