Summary

• Tighten the gap between a list and its introductory paragraph, including bold section labels.
• Restore spacing above later Markdown headings by correcting a selector that applied the first-heading exception to every heading. Keep Streamdown's existing message-edge handling.

Type of Change

• Bug fix

Testing

• Browser QA with the real ChatContent renderer and production CSS: 12 combinations of desktop/mobile widths, light/dark themes, and static/streaming rendering. Verified list introductions, headings (including first/later headings inside quotes), nested ordered/unordered lists, task lists, wrapping, and stable layout on settling.
• Confirmed the paragraph/list and later-heading checks fail before their respective fixes. Paragraph/list gaps change from 18.75px to 8px; later headings regain their 24px top margin. Existing paragraph and nested-list spacing remain unchanged. Local JSON report and screenshots captured.
• The initial full-parallel test run hit a sanitizer timing benchmark; the complete run passed with four workers and unchanged assertions.
• ChatContent's 16 existing tests, root VITEST_MAX_WORKERS=4 bun run test, bun run lint, bun run type-check, bun run check:audits, block-registry audit, and all four ship artifact generators.
