16mo EulerSwapCustom AMM curve hook backed by Euler lending vault positions. Executes all swap logic in `beforeSwap` via a `BeforeSwapDelta` return, routing input tokens into and output tokens out of Euler vaults using a configurable curve invariant. Liquidity addition and donation are permanently blocked via revert. Deployed as delegatecall proxy instances pointing to an immutable implementation.
