add hover lift up effect for the feature cards

[vanshika-738]

The lift-up hover effect is a simple and modern UI animation applied to cards to make them feel more interactive and visually appealing. When the user hovers over a card, the card slightly moves upward and gains a subtle shadow. This creates a sense of depth and makes the card appear “active,” improving user engagement.

This is a good enhancement idea — hover interactions help improve the UI experience and make the feature cards feel more dynamic.

Before implementation, let's define a few points:

1. The hover effect should be subtle and consistent with the existing design system.
2. Animation duration should be between 200–300ms for smooth interaction.
3. Ensure the effect is responsive and does not break on mobile devices (touch devices should not trigger hover).
4. Accessibility check: hover effect should not be the only visual cue.

Once these points are clear, you can proceed with adding the hover animation to the feature cards.
