 * Mobile Browser URL Bar Strategy
 * 
 * On iOS Safari/Chrome, the URL bar collapses when the user scrolls DOWN.
 * Our app uses 100dvh with internal scrolling, so we need to:
 * 1. Make the page slightly taller than viewport (scrollable)
 * 2. Use dvh units so the app resizes when URL bar collapses
 * 3. Keep the app fixed at top while body is scrollable
 * 
 * The user's natural scroll gesture will collapse the URL bar.
