• Added functionality to handle direct navigation to pages with hash links, ensuring the correct table of contents link is highlighted.
• Introduced a temporary disable feature for the intersection observer during hash navigation to prevent unwanted updates.
• Adjusted the root margin of the observer for improved sensitivity in detecting visible headings.
