## Testing Dark Mode

To test the dark mode changes:

1. **In browser DevTools:**
   - Open DevTools → Right-click on `<html>` element
   - Add `class="dark"` to the html tag
   - All pages should display properly with dark background and light text

2. **With theme toggle (if available):**
   - Look for theme toggle in navbar
   - Pages should seamlessly switch between light and dark modes

3. **Verify:**
   - Background gradients display correctly
   - All text is readable in both modes
   - Form inputs show text clearly in both modes
   - Buttons are clickable and properly styled
   - Cards have proper contrast
