1//! User-facing configuration. Resolved from (precedence high → low):
2//!   1. CLI flags
3//!   2. environment variables prefixed with `ONOSENDAI_`
4//!   3. TOML config file (`$XDG_CONFIG_HOME/ono-sendai/config.toml`)
5//!   4. compiled-in defaults
6//!
7//! The resolver lives in the binary crate; this module only declares the
8//! shape so that every other crate can reason about it.
