I can see the current structure. Now I'll implement the required changes:

1. Header improvements: Reduce default height, make it transparent on homepage, add scroll shrinking effect
2. Sectors section: Make cards fully clickable and add hover interactions

Let me start with the header:

Now let me update the page padding to account for the reduced default header height:

Now let me update the sectors section to make cards fully clickable with better hover interactions:

I've implemented all the requested changes:

Header/Navbar Improvements:

• Reduced default header height from h-36 md:h-44 to h-28 md:h-32 for a cleaner, more premium feel on homepage
• Made navbar glass-like with bg-white/5 backdrop-blur-sm when not scrolled for visual transparency and spaciousness
• On scroll, header shrinks to h-20 md:h-24 with padding reduction (py-2 md:py-2.5) for a compact sticky state
• Added smooth 500ms transitions throughout for premium feel
• Logo, badge, and navigation items remain unchanged in size and typography—only container shrinks
• Updated page padding to pt-28 md:pt-32 to match the new default header height

Sectors Cards Enhancements:

• All six cards are fully clickable with href="#projects" linking to the Projects section
• Added lift effect with hover:-translate-y-2 for subtle elevation on hover
• Enhanced shadow with hover:shadow-2xl for depth
• Improved gradient overlay on hover with blue accent color (group-hover:from-blue-600/80)
• Smooth 500ms transitions throughout for premium feel
• Cursor pointer and better visual feedback already in place

I can see the issue - the closing > is missing on line 42 after the closing parenthesis and brace. Let me fix it:

Fixed the syntax error! The closing > was missing on the <div> tag. The header now has the proper JSX structure with the className closing properly and the div opening tag complete.
