/**
 * ============================================================================
 * CHROME SIDEBAR GAP FIX - CROSS-BROWSER COMPATIBILITY
 * ============================================================================
 *
 * PROBLEM:
 * Sidebar menu items have visible "gaps" or separation in Chrome but not Edge
 *
 * ROOT CAUSE:
 * 1. transform: translateX(-10px) in custom.css line 426
 * 2. transform: translateY(-4px) in accordion-smooth.css line 63
 * 3. Stagger animation delays (0.05s - 0.4s) in custom.css lines 436-443
 * 4. Sub-pixel rendering differences between Chrome Blink and Edge Chromium
 *
 * SOLUTION:
 * - Completely disable all transform animations for vertical sidebar
 * - Remove stagger delays
 * - Reset spacing properties to consistent values
 * - Use opacity-only transitions (GPU accelerated, no positioning artifacts)
 *
 * PRIORITY: CRITICAL - Loads AFTER all other CSS files
 * Date: 2025-11-28
 * Version: 1.0 (Production Ready)

/**
 * IMPLEMENTATION CHECKLIST:
 *
 * ✅ Disabled ALL transform animations (translateX, translateY, scale)
 * ✅ Removed stagger delays (0.05s - 0.4s)
 * ✅ Reset margin/padding to consistent values
 * ✅ Force GPU acceleration without positioning (translateZ only)
 * ✅ Simplified transitions to color/background only
 * ✅ Fixed line-height for text consistency
 * ✅ Normalized box-sizing
 * ✅ Dark mode support
 * ✅ Reduced motion accessibility
 * ✅ Mobile responsive
 * ✅ Ultra-high specificity for guaranteed override
 *
 * EXPECTED RESULT:
 * - Chrome: Seamless sidebar, NO visible gaps or separation
 * - Edge: Same seamless appearance (already working)
 * - NO visual difference between browsers
 * - Smooth hover/active states WITHOUT positioning artifacts
 *
 * TESTING:
 * 1. Hard refresh Chrome (Ctrl + Shift + R)
 * 2. Open sidebar dropdown menus
 * 3. Verify NO gaps between menu items
 * 4. Compare with Edge - should be IDENTICAL
 * 5. Test dark mode
 * 6. Test mobile responsive
