//! System contracts for the `MegaETH` EVM.
//!
//! This crate provides bytecode constants for system contracts used by mega-evm.
//! When building from the repository with Foundry installed, the build script validates that
//! the pre-generated constants match the compiled Solidity source.
//! When building from a published crate (without Foundry), the pre-generated constants are used
//! directly.
