Deposit Only	Deposit collateral without minting	depositAssetToMint(uint256 assetAmount, 0)
Mint Only	Mint nUSD against existing collateral	mint(address onBehalfOf, uint256 amount)
Repay	Burn nUSD without withdrawing	burn(address onBehalfOf, uint256 amount)

Example: Deposit and Mint

// Approve collateral for deposit
IERC20(collateralToken).approve(vaultAddress, collateralAmount);

// Deposit collateral and mint nUSD in one transaction
IVault(vaultAddress).depositAssetToMint(collateralAmount, nusdAmount);

// Check updated position
(uint256 collateral, uint256 debt) = IVault(vaultAddress).positions(userAddress);

Example: Withdraw After Repaying

// Approve nUSD for burning
IERC20(nUSDAddress).approve(vaultAddress, debtAmount);

// Burn nUSD to reduce debt
IVault(vaultAddress).burn(userAddress, debtAmount);

// Withdraw collateral
