When to skip or lighten it

Pattern Definition:Frequently asked questions
Translate existing message or regenerate?
Both are valid. Regenerate when tone must adapt; translate when speed matters.
Preserve formatting?
Keep lists, code blocks, and citations stable across language swaps.
Lang-toggle vs real-time translation?
Lang-toggle switches written AI output. Real-time translation handles live spoken conversation.
Default language?
