//! The driver-domain context a command executes against (ADR-051 D8).
//!
//! The database path / chain id / node URIs are resolved through the
//! `degenbot-config` resolvers — the SAME cascades the Python console reads —
//! over an injectable [`EnvVars`] seam (never `std::env`), with the CLI override
//! values the argv facade threaded in.
