💡 What: Added
role="presentation"to purely visual<table>elements and converted decorative markdown images to<img>tags withalt="" aria-hidden="true".🎯 Why: To improve accessibility. Using
<table>for visual layout grids in Markdown causes screen readers to incorrectly announce them as tabular data. Decorative images without properaria-hiddenattributes create unnecessary noise for visually impaired users.📸 Before/After: (Visual appearance is unchanged, but DOM is semantically different)
♿ Accessibility: Prevents layout tables and decorative images from polluting the screen reader experience.
