     * clashing], which can potentially be used in an attack, this contract uses the
     * https://blog.openzeppelin.com/the-transparent-proxy-pattern/[transparent proxy pattern]. This pattern implies two
     * things that go hand in hand:
     *
     * 1. If any account other than the admin calls the proxy, the call will be forwarded to the implementation, even if
     * that call matches the {ITransparentUpgradeableProxy-upgradeToAndCall} function exposed by the proxy itself.
     * 2. If the admin calls the proxy, it can call the `upgradeToAndCall` function but any other call won't be forwarded to
     * the implementation. If the admin tries to call a function on the implementation it will fail with an error indicating
     * the proxy admin cannot fallback to the target implementation.
     *
     * These properties mean that the admin account can only be used for upgrading the proxy, so it's best if it's a
     * dedicated account that is not used for anything else. This will avoid headaches due to sudden errors when trying to
     * call a function from the proxy implementation. For this reason, the proxy deploys an instance of {ProxyAdmin} and
     * allows upgrades only if they come through it. You should think of the `ProxyAdmin` instance as the administrative
     * interface of the proxy, including the ability to change who can trigger upgrades by transferring ownership.
     *
     * NOTE: The real interface of this proxy is that defined in `ITransparentUpgradeableProxy`. This contract does not
     * inherit from that interface, and instead `upgradeToAndCall` is implicitly implemented using a custom dispatch
     * mechanism in `_fallback`. Consequently, the compiler will not produce an ABI for this contract. This is necessary to
     * fully implement transparency without decoding reverts caused by selector clashes between the proxy and the
     * implementation.
     *
     * NOTE: This proxy does not inherit from {Context} deliberately. The {ProxyAdmin} of this contract won't send a
     * meta-transaction in any way, and any other meta-transaction setup should be made in the implementation contract.
     *
     * IMPORTANT: This contract avoids unnecessary storage reads by setting the admin only during construction as an
     * immutable variable, preventing any changes thereafter. However, the admin slot defined in ERC-1967 can still be
     * overwritten by the implementation logic pointed to by this proxy. In such cases, the contract may end up in an
     * undesirable state where the admin slot is different from the actual admin.
     *
     * WARNING: It is not recommended to extend this contract to add additional external functions. If you do so, the
     * compiler will not check that there are no selector conflicts, due to the note above. A selector clash between any new
     * function and the functions declared in {ITransparentUpgradeableProxy} will be resolved in favor of the new one. This
     * could render the `upgradeToAndCall` function inaccessible, preventing upgradeability and compromising transparency.

     * @dev Contract module that allows children to implement role-based access

     * members except through off-chain means by accessing the contract event logs. Some
     * applications may benefit from on-chain enumerability, for those cases see
     * {AccessControlEnumerable}.
     *
     * Roles are referred to by their `bytes32` identifier. These should be exposed
     * in the external API and be unique. The best way to achieve this is by
     * using `public constant` hash digests:
     *
     * ```solidity
     * bytes32 public constant MY_ROLE = keccak256("MY_ROLE");
     * ```
     *
     * Roles can be used to represent a set of permissions. To restrict access to a
     * function call, use {hasRole}:
     *
     * ```solidity
     * function foo() public {
     *     require(hasRole(MY_ROLE, msg.sender));
     *     ...
     * }
     * ```
     *
     * Roles can be granted and revoked dynamically via the {grantRole} and
     * {revokeRole} functions. Each role has an associated admin role, and only
     * accounts that have a role's admin role can call {grantRole} and {revokeRole}.
     *
     * By default, the admin role for all roles is `DEFAULT_ADMIN_ROLE`, which means
     * that only accounts with this role will be able to grant or revoke other
     * roles. More complex role relationships can be created by using
     * {_setRoleAdmin}.
     *
     * WARNING: The `DEFAULT_ADMIN_ROLE` is also its own admin: it has permission to
     * grant and revoke this role. Extra precautions should be taken to secure
     * accounts that have been granted it. We recommend using {AccessControlDefaultAdminRules}
     * to enforce additional security measures for this role.

    /**
     * @dev 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]
     * ```

     * @dev https://eips.ethereum.org/EIPS/eip-712[EIP 712] is a standard for hashing and signing of typed structured data.
     *
     * The encoding scheme specified in the EIP requires a domain separator and a hash of the typed structured data, whose
     * encoding is very generic and therefore its implementation in Solidity is not feasible, thus this contract
     * does not implement the encoding itself. Protocols need to implement the type-specific encoding they need in order to
     * produce the hash of their typed data using a combination of `abi.encode` and `keccak256`.
     *
     * This contract implements the EIP 712 domain separator ({_domainSeparatorV4}) that is used as part of the encoding
     * scheme, and the final step of the encoding to obtain the message digest that is then signed via ECDSA
     * ({_hashTypedDataV4}).
     *
     * The implementation of the domain separator was designed to be as efficient as possible while still properly updating
     * the chain id to protect against replay attacks on an eventual fork of the chain.
     *
     * NOTE: This contract implements the version of the encoding known as "v4", as implemented by the JSON RPC method
     * https://docs.metamask.io/guide/signing-data.html[`eth_signTypedDataV4` in MetaMask].
     *
     * NOTE: In the upgradeable version of this contract, the cached values will correspond to the address, and the domain
     * separator of the implementation contract. This will cause the {_domainSeparatorV4} function to always rebuild the
     * separator from the immutable values, which is cheaper than accessing a cached version in cold storage.

     * https://eips.ethereum.org/EIPS/eip-2612[EIP-2612].
     *
     * Adds the {permit} method, which can be used to change an account's ERC20 allowance (see {IERC20-allowance}) by
     * presenting a message signed by the account. By not relying on {IERC20-approve}, the token holder account doesn't
     * need to send a transaction, and thus is not required to hold Ether at all.
     *
     * ==== Security Considerations
     *
     * There are two important considerations concerning the use of `permit`. The first is that a valid permit signature
     * expresses an allowance, and it should not be assumed to convey additional meaning. In particular, it should not be
     * considered as an intention to spend the allowance in any specific way. The second is that because permits have
     * built-in replay protection and can be submitted by anyone, they can be frontrun. A protocol that uses permits should
     * take this into consideration and allow a `permit` call to fail. Combining these two aspects, a pattern that may be
     * generally recommended is:
     *
     * ```solidity
     * function doThingWithPermit(..., uint256 value, uint256 deadline, uint8 v, bytes32 r, bytes32 s) public {
     *     try token.permit(msg.sender, address(this), value, deadline, v, r, s) {} catch {}
     *     doThing(..., value);
     * }
     *
     * function doThing(..., uint256 value) public {
     *     token.safeTransferFrom(msg.sender, address(this), value);
     *     ...
     * }
     * ```
     *
     * Observe that: 1) `msg.sender` is used as the owner, leaving no ambiguity as to the signer intent, and 2) the use of
     * `try/catch` allows the permit to fail and makes the code tolerant to frontrunning. (See also
     * {SafeERC20-safeTransferFrom}).
     *
     * Additionally, note that smart contract wallets (such as Argent or Safe) are not able to produce permit signatures, so
     * contracts should have entry points that don't rely on permit.
