//! Persistent settings store and config-path helpers.
//!
//! Settings are kept in a single JSON file under the OS-specific config
//! directory (resolved through [`directories::ProjectDirs`]) and exposed as a
//! per-type [`Settings`] map: `bool`, `i32`, `f32`, `String`, raw bytes,
//! and `Vec<String>`. Both the UI and the server side use the same
//! [`rpfm_ipc::settings_keys`] constants when reading and writing, so a typo
//! becomes a compile error rather than a silently-missed setting.
