[surya4419]

This pull request fixes the issue where the "Load Sample" and "Share" buttons in the body section did not update their UI on dark/light mode toggle. These buttons now respond correctly to theme changes.

Changes

• Applied dark theme classes to Load Sample and Share buttons
• Refactored button styling logic to support theme responsiveness
