1//! Boolean-like string parsing.
2//!
3//! This module normalizes common human-facing boolean spellings used in runtime
4//! configuration rows and environment-like settings. It deliberately returns an
5//! `Option<bool>` so callers can decide whether invalid input should fail
6//! closed, fall back to a default, or surface a product-specific validation
7//! error.
8
9/// Parses common boolean spellings such as `true`, `1`, `yes`, and `on`.
