/**
 * @dev ERC721DynamicIdsUpgradeable is a clever trick to make trading NFTs with dynamic traits safe.
 *
 * Stable value represented by an NFT is a prerequisite for safe trading today.
 *
 * If the value of an NFT can be changed by the seller, they can rug the buyer by using up the NFT before they accept they buy offer.
 *
 * Dynamic ids solve that problem by burning the old NFT and minting a new one every time the value of an NFT changes.
 * That invalidates all offers made for an NFT before the value changed.
 *
 * A naive implementation would perform literal burn and mint every time but that’s extremely gas-inefficient.
 *
 * A clever implementation changes NFT id every time its value changes, emits Transfer events as if the NFT was
 * burned and minted, while in reality no storage writes are performed.
 *
 * For this to work, we use 32-byte numbers as ids where:
 * - the first 16 bytes are calculated during the mint and never change again.
 * - the last 16 bytes are calculated every time the value changes.
 *
 * This results in a new id being issued every time the value changes while keeping some unique part of it (the first 16 bytes)
 * constant so that we can keep track of owners, allowances, and other properties.
 *
 * An id emitted in Transfer events and visible to the outside world is called a publicId.
 * An id used internally to keep track of things is called a mintId.
 *
 * The last 16 bytes of mintId MUST equal zero.
 *
 * A watchful reader will notice that by splitting ids in two 16-bytes long parts, we increase the risk of id collision.
 * This risk is described by The Birthday Problem.
 * For 16-bytes long ids, the risk of collision raises above 1% after generating 52 * 10^18 perfectly random ids.
 * That makes a collision unlikely for most protocols using this technique.
 *
 * Note that _safeMint function prevents minting NFTs with an id that already exists.
 *
 * To prevent DOS due to id collision, it’s advised protocols mix in block.timestamp into the mintId payload.
 *
 * Note: this contract requires a patch on OpenZeppelin ERC721 implementation such that the _update function does not emit
 * the Transfer event because it only has access to a mintId while Transfer events should be emitted using publicId.
 *
 * @notice This contract is marked as abstract because inheriting contract MUST override _getPayload function so that it returns
 * a unique payload every time the value of the NFT changes.

/**
 * @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();
 * }
 * ```
