/**
 * @fileoverview The prompt-cache keep-warm rows (Session Options → Respawn switch, App Settings
 * → Automation default and cap) in Chinese (zh-CN): each label and description runs through
 * the real translator over the real index.html in JSDOM and reads in Chinese with no English
 * left beyond the product names, and every new key, the toggle toasts included, is in the
 * dictionary exactly once (a repeated key in the object literal silently replaces the first).
