* @custom:security-contact [email protected]
* @notice Allows users to stake assets and receive shares, with support for reward distribution.
* @dev Integrates with ProtocolStaking and OperatorRewarder contracts. Inspired by ERC7540 but not fully compliant.
* Also inherits ERC1363 to ease of users with potential OperatorStaking contract migrations.
*
* NOTE: This contract supports slashing on the `ProtocolStaking` level, meaning that the overall stake of this contract
* may decrease due to slashing. These losses are symmetrically passed to restakers on the `OperatorStaking` level.
* Slashing must first decrease the `ProtocolStaking` balance of this contract before affecting pending withdrawals.
