/**
 * Localized display names for the built-in audio providers.
 *
 * The `name` field in `ASR_PROVIDERS` / `TTS_PROVIDERS` is a registry label, not
 * a UI string: several are written in Chinese (`浏览器原生 ASR (Web Speech API)`,
 * `Qwen ASR (阿里云百炼)`). Rendering it directly leaks Chinese into every other
 * locale, so any surface that shows a provider to the user must resolve the
 * name through i18n instead.
 *
 * Kept here rather than in a component so the settings dialog and the
 * generation toolbar cannot drift apart on what a provider is called.
