Describe the bug

On switching between themes , the header logo disappears in the dark mode .

Expected behavior

I will add a separate logo variant for dark mode (for example, a white/light-colored logo).
Use theme-based conditional rendering or CSS classes to switch logos when the theme changes.
Ensure the logo path/assets are correctly loaded in dark mode.
Verify visibility and contrast against the dark background.
