## Summary by CodeRabbit
- Style
- Improved emoji alignment in callout blocks. The emoji now adjusts its
top spacing based on the first line’s heading level, ensuring better
vertical alignment with headings (H1–H6) and more consistent visual
balance across different callout contents.
- Maintains existing margins and layout behavior otherwise, resulting in
a cleaner, more polished appearance without affecting functionality.
