Bottom Navigation Bar Overlapping Page Content in Bolt App

The fixed bottom navigation bar in your Bolt.new app covers the last items on every page. Users cannot see or tap buttons, form submit actions, and the last few items in lists are permanently hidden behind the nav bar. Scrolling to the bottom doesn't help because the nav bar moves with the viewport.

This is especially problematic on pages with action buttons at the bottom (checkout, submit, save), infinite scroll lists, and chat interfaces where the input field is at the bottom. Users literally cannot complete key actions because the navigation bar is covering them.

The problem gets worse on iPhones with the home indicator bar (iPhone X and later), where the safe area inset adds additional space that pushes the nav bar higher but doesn't account for the content behind it.
