//! Bilingual (en/zh) catalog for user-facing runtime messages.
//!
//! Refusals, approval prompts, and recovery notices are product surface,
//! not log lines — they should read like a person wrote them, in the
//! operator's language. `user_message_language` selects `en` (default,
//! preserves historical output), `zh`, or `bilingual` (both blocks).
//! Approval reply keywords are always recognized in both languages
//! regardless of the render language.
