               * @dev This contract implements a proxy that is upgradeable through an associated {ProxyAdmin} instance.
               *
               * To avoid https://medium.com/nomic-labs-blog/malicious-backdoors-in-ethereum-proxies-62629adf3357[proxy selector
               * 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 This contract implements a proxy that is upgradeable through an associated {ProxyAdmin} instance.
               *
               * To avoid https://medium.com/nomic-labs-blog/malicious-backdoors-in-ethereum-proxies-62629adf3357[proxy selector
               * 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 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 This contract implements a proxy that is upgradeable through an associated {ProxyAdmin} instance.
               *
               * To avoid https://medium.com/nomic-labs-blog/malicious-backdoors-in-ethereum-proxies-62629adf3357[proxy selector
               * 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 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]
               * ```

               * ==== 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.

               * ==== 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.

              /**
               * @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]
               * ```
               * /// @custom:oz-upgrades-unsafe-allow constructor
               * constructor() {
               *     _disableInitializers();
               * }

               * 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.

               * @dev This contract implements a proxy that is upgradeable through an associated {ProxyAdmin} instance.
               *
               * To avoid https://medium.com/nomic-labs-blog/malicious-backdoors-in-ethereum-proxies-62629adf3357[proxy selector
               * 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 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();
               * }
               * ```
