//! Loading and translating configuration between Lua and Rust.
//!
//! The real application consumes Lua configuration files. This module exposes
//! helpers to load them, merge user values with defaults, and convert between
//! Lua tables and strongly typed Rust structures. Integration tests reuse these
//! APIs to fabricate configurations dynamically.
