The assistant-ui markdown defaults (heading margins up to 32px, 20px paragraph margins, 24px list indent, 24px blockquote padding, 16px code padding) are tuned for the full-page Thread and waste space in the narrow sidebar column. Scope tighter spacing to .ask-fabro-sidebar for headings, paragraphs, lists, blockquotes, and code blocks. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
