//! EIP-2780: Reduce intrinsic transaction gas
//!
//! Replaces the legacy `21,000` intrinsic base with a decomposed model that
//! prices a reduced sender base plus additional `to`- and `value`-based
//! charges. Composes with EIP-8037 (state gas) and EIP-8038 (state-access
//! costs) starting at the Amsterdam hardfork.
/// Reduced intrinsic base cost charged to `tx.sender` (execution-specs `TX_BASE`).
