/**
 * Global Modal Z-Index Fix
 * 
 * Ensures ALL modals across the entire webapp appear above navbar and are fully functional.
 * 
 * Z-Index Hierarchy:
 * - Navbar: 10000
 * - Modal Backdrop (with blur): 10001 (above navbar, below modal)
 * - Modal Content: 10002 (above backdrop and navbar)
 * 
 * CRITICAL: Backdrop blur must be BELOW modal content, not over it.
 * 
 * This file must load after Bootstrap CSS but before other custom CSS.
 * This is a GLOBAL solution that works everywhere.
