1//! SCV's configuration: the schema of `config.toml` ([`schema`]), how the
2//! layers are read and merged ([`load`]), what each value must satisfy and
3//! what a project may change ([`validate`]), and the settings the runtime,
4//! tools, and provider are built from ([`runtime`]).
5//!
6//! The `scv` command line reads it too: `scv config show` lists every
7//! [`Setting`] with its origin, and `scv agents` finds the agent homes.
