Summary accessibility

[Ovgodd]

Bug Report

Problematic behavior
The Table of Contents (Summary) lacked accessibility and semantic structure:

• Screen readers did not correctly announce it
• Focus ring was too large and inconsistent
• Poor keyboard navigation

Expected behavior/code

• TOC should use semantic HTML (nav, ul, li)
• ARIA attributes should be applied (aria-label, aria-selected, etc.)
• Focus styling
• Keyboard navigation with Tab and Enter should behave like mouse click

Steps to Reproduce

1. Open a document with a summary section
2. Try navigating with Tab or a screen reader
3. Notice inconsistent focus, lack of semantic announcements, and weak accessibility

Possible Solution

• Add semantic elements
• Use ARIA
• Use consistent focus behavior
