//! TOML config + multi-gateway resolution.
//!
//! A user may define named defaults in `~/.cardanowall/config.toml` (overridable
//! via `CARDANOWALL_CONFIG_PATH`) so they need not pass `--gateway` /
//! `--arweave-gateway` / `--blockfrost` on every invocation. The resolver applies
//! the precedence `flags > env > config-file > built-in default`.
