/**
 * @dev Contract module that allows children to implement role-based access
 * control mechanisms. This is a lightweight version that doesn't allow enumerating role
 * 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 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. Relying on the value of the admin slot
 * is generally fine if the implementation is trusted.
 *
 * 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.
