Feature: Add working dark mode toggle to website #3
Description
The website currently only supports light mode. A dark mode toggle should be added to improve accessibility and user comfort, especially during night-time usage.
Expected Behavior:
A toggle button (e.g., in navbar or header) that switches the theme between light and dark.
The dark theme should apply across all components like navbar, cards, footer, etc.
Store user preference using localStorage to persist across sessions.
Suggested Approach:
Use Tailwind CSS's dark variant or custom CSS variables.
Use a state variable or class toggle to switch themes dynamically.
Additional Context:
This will enhance the UX and is a great addition to the overall design of the News Aggregator.
