Notes for Reviewers

Summary

Fixed the job details card border styling to support both light and dark themes.

Changes

• Replaced hardcoded border colors with theme-aware color tokens.

Result

• Maintains the existing appearance in light mode while improving visibility in dark mode.

Before

Thanks @Bakul2006 , the approach looks good to me.

Replacing the hardcoded border colours with theme-aware values is the right fix here, since the issue was specifically caused by the card border blending into the dark theme background.
