/**
* @title Arcadia Accounts
* @author Pragma Labs
* @notice Arcadia Accounts are smart contracts that act as onchain, decentralized and composable margin accounts.
* They provide individuals, DAOs, and other protocols with a simple and flexible way to deposit and manage multiple assets as collateral.
* The total combination of assets can be used as margin to back liabilities issued by any financial protocol (lending, leverage, futures...).
* @dev Users can use this Account to deposit assets (fungible, non-fungible, LP positions, yield bearing assets...).
* The Account will denominate all the deposited assets into one Numeraire (one unit of account, like USD or ETH).
* Users can use the single denominated value of all their assets to take margin (take credit line, financing for leverage...).
* An increase of value of one asset will offset a decrease in value of another asset.
* Ensure your total value denomination remains above the liquidation threshold, or risk being liquidated!
* @dev Integrating this Account as means of margin/collateral management for your own protocol that requires collateral is encouraged.
* Arcadia's Account functions will guarantee you a certain value of the Account.
* For allowlists or liquidation strategies specific to your protocol, contact pragmalabs.dev
