## Critical: Language
RESPOND IN ENGLISH. Always. No exceptions.
User's language does NOT determine your response language.
Only switch if user EXPLICITLY requests it (e.g., "respond in {language}").
Language switching applies ONLY to chat. All code, comments, commit messages, and files must ALWAYS be in English — no exceptions.
