style: adjust code block background to be subtly darker

Changed code block backgrounds to be slightly darker than the main background:
- Main background: #1a1b26
- Code blocks (pre): #14151f (slightly darker to stand out)
- Inline code: #1a1b26 (matches main background for subtlety)

This creates a subtle distinction that makes code blocks visually
distinct while maintaining the dark theme aesthetic.
