Feature Request: Add Light Mode Support #83

The website currently supports only dark mode. There is no option available for users to switch to a light theme.

Steps to Observe

1. Open the website
2. Navigate through the homepage and other sections
3. Observe that only dark theme is available
4. No toggle/button exists for switching to light mode

Expected Behavior

Users should have the option to switch between dark mode and light mode according to their preference.

Current Behavior

The website is restricted to dark mode only.

Suggested Improvement

Implement a theme toggle (Dark/Light mode) using CSS variables or theme state management for better accessibility and user experience.
