1//! The embedded preset library: curated config fragments shipped with
2//! declint, imported as `import: preset:<name>`.
3//!
4//! The presets are ordinary YAML config files living in this crate's
5//! `presets/` directory (so they ship inside the published package) and
6//! embedded at compile time — binaries are self-contained, and CI needs
7//! nothing beyond the executable.
