I'll adjust the logos to align them at their bottom edges:

I've adjusted the positioning of the CareDx and Vercel logos to align them at their bottom edges by:

1. Changing the flex container's alignment from items-center to items-end - this aligns all items in the container at their bottom edges
2. Added a small bottom padding (pb-[1px]) to the CareDx logo to fine-tune the alignment
3. Maintained the existing sizes of both logos (CareDx at h-8 and Vercel triangle at h-6)

These changes ensure that both logos now share a common baseline, creating a more visually unified appearance while maintaining the overall balance and responsiveness of the header. The logos will remain bottom-aligned across all screen sizes.

I'll implement smooth scrolling functionality for the header navigation links:

I've implemented smooth scrolling functionality in the header component with the following enhancements:

1. Added a smooth scrolling function:

   • Created a handleSmoothScroll function that:

     • Prevents default link behavior
     • Closes the mobile menu if it's open
     • Calculates the target position with an offset for the header height
     • Smoothly scrolls to the target section
     • Updates the URL hash without causing additional scrolling

2. Applied global smooth scrolling:

   • Added a useEffect hook that sets scrollBehavior: "smooth" on the document element
   • Includes a cleanup function to remove the style when the component unmounts

3. Updated navigation links:

   • Changed Next.js Link components to regular <a> tags with href attributes
   • Added onClick event handlers to each link that call the smooth scrolling function
   • Applied the changes to both desktop navigation and mobile menu links

4. Added header offset:

   • Calculated the header height (64px) to offset the scroll position
   • This ensures sections aren't partially hidden behind the sticky header

5. Maintained responsiveness:

   • The implementation works across all screen sizes
   • Mobile menu automatically closes after a link is clicked

These changes provide a seamless, animated scrolling experience when navigating between sections of the page, enhancing the overall user experience while maintaining the existing design and functionality.
