[Feature] : toggle for light/dark theme #528
Description
Is your feature request related to a problem? Please describe.
Users can't switch between light and dark themes manually.
Describe the solution you'd like
Add a toggle button to let users switch themes easily. Save their choice using localStorage so it stays even after refresh.
Describe alternatives you've considered
- Auto-detect system theme (already works, but no manual control)
- Theme setting in user profile (less convenient
Additional context
This improves accessibility and user experience. Can be done using Tailwind’s dark mode toggle or React context.
