-/**
- * Key Points:
- *
- * 1. pb-20 = padding-bottom on mobile
- *    - 5rem (80px) to accommodate navbar height + safe area
- *    - Prevents content from being hidden behind navbar
- *
- * 2. md:pb-0 = no padding on desktop
- *    - Navbar is hidden on desktop (md:hidden in navbar component)
- *    - So no padding needed
- *
- * 3. flex flex-col min-h-screen
- *    - Creates flexible column layout
- *    - Ensures navbar stays at bottom even with short content
- *
- * 4. dir="rtl"
- *    - Sets RTL direction for Persian text
- *    - Applies to all child elements
- *
- * 5. <Outlet />
- *    - React Router renders child routes here
- *    - Each page component renders inside the main tag
