Dark Mode of AMP Website.

### Description

AMP website in light mode looks classic but in **dark mode** it will enhance more and make it more better and in the **footer** there is not **animation on hover** of text that should be imporved.

### Alternatives Considered

We go with the dark mode, that having toggle option to change and default is dark mode.

### Additional Context

_No response_

The issue does not name files, tests, or an entry point. First locate the AMP website styling and footer implementation, then clarify the dark-mode toggle/default behavior and the intended footer hover animation; done means both changes are implemented consistently on the website.
