- Fixed white background in code blocks by adding custom CSS
- Code blocks now use dark background (#1a1b26 for pre, #16161e for code)
- Inline code matches theme colors
- Added copy buttons to all code blocks
- Button appears on hover (top-right corner)
- Shows 'Copy' → 'Copied!' feedback
- Uses Clipboard API for copying code
- Copy buttons styled to match documentation theme
This improves the dark mode documentation experience with better
code block visibility and usability.
