When scrolling: as the nav bar transitions to having a bottom border and a blurred background, the layout of the icons would shift up slightly due to the bottom border size changing. To fix this I've made it so that the bottom border is always 1px but is transparent by default. This prevents the layout shift when scrolling.

Pull request overview
This PR fixes a minor layout shift issue that occurs when scrolling causes the navigation bar to transition from transparent to having a visible bottom border. The fix ensures the border remains 1px at all times, only changing from transparent to visible, which prevents the navigation icons from shifting vertically during scroll.
Key changes:
- Modified the CSS rule for the navigation bar to maintain a constant 1px transparent border instead of no border when at the top of the page

Super tiny PR but spotted this while experimenting with the latest release candidate.
