I18nText — Internationalized Text

All user-facing text (display names, hints, placeholders, etc.) uses the I18nText type:

type I18nText = {
  en_US: string // English (required)
  zh_Hans?: string // Simplified Chinese (optional)
  [locale: string]: string // Other languages
}

Example:

{
  display_name: {
    en_US: "API Key",
    zh_Hans: "API 密钥"
  }
}

Rule: en_US is always required. When the current language is not provided, it falls back to en_US.
