The file has been updated. The changes include:
- Proper DOCTYPE and head section with meta tags
- Max-width constraint (800px) with centered content so text doesn't span the full page
- Modern system fonts (-apple-system, BlinkMacSystemFont, Segoe UI, Roboto) instead of Times New Roman
- Monospace fonts preserved for code blocks (SF Mono, Monaco, Consolas, etc.)
- Styled code blocks with a light gray background and rounded corners
- Reasonable line-height (1.6) for better readability
- Styled notes header with a subtle background
The CSS uses !important to override the inline styles that were pasted from Claude's interface. You can open the file in a browser to see the improved layout.
