Let me search for the bottom navigation menu section:

I found the bottom navigation. Now I'll make the changes:

1. Increase button size in the bottom navigation
2. Change it from fixed bottom-0 (bottom of page) to stick at the bottom of viewport

Now I need to adjust the main content area to account for the taller bottom navigation. Let me find the main content wrapper:

I've updated the bottom navigation menu with these changes:

Updates made:

1. Bigger buttons - Increased icon size from w-5 h-5 to w-6 h-6, text size from text-[9px] to text-[10px], and added padding (py-2 px-3)
2. Taller navigation bar - Increased height from h-16 to h-20 for more spacious button area
3. Better spacing - Added gaps between elements and hover effects with background color change
4. Fixed at viewport bottom - The navigation stays at the bottom of the visible screen (not page), and the content now has pb-24 padding on mobile to prevent overlap

The navigation buttons now have better touchability and are more prominent on mobile devices.

I pulled the latest changes from v0/nvht25052002-2777-9b5e3655 in AGENTS.RKIX3.
