Improve Homepage UX: Navigation Layout, Hero Section Content Clarity & Mobile Sticky Header

[whyrupesh]

Hi Maintainers 👋,
I want to fix UI of home page of argo website.

1. Navigation ( Leaving some space will make it more better ).
2. Hero section ( Content of Hero section are not clearly visible, which not looks good, i want to make it better )
3. Navigation in phone view is disappears on scroll in mobile view. It should be there on top always, So i want to fix that as well.
   Make the navigation bar sticky so it remains visible while scrolling for easier access to key sections.

I’d love to get started with these changes and continue contributing if they align with the team’s design goals.
