1//! Bilingual (EN/TR) text selection, shared by every Rust surface.
2//!
3//! Every user-facing string in the engine and CLI goes through
4//! [`Language::text`] so we never ship a one-language string (project rule).
5//! Detection honors an explicit `CONTEXTBAR_LANG=en|tr` override first, then
6//! the standard locale env vars.
