   RECOMMENDATIONS SECTION
   ============================================ */
/*
 * COLOR VARIATIONS TO TRY:
 * 
 * 1. Warmer Palette:
 *    --color-bg-primary: #1a1625;
 *    --gradient-primary: linear-gradient(135deg, #f093fb 0%, #f5576c 100%);
 * 
 * 2. Cooler Palette:
 *    --color-bg-primary: #0d1117;
 *    --gradient-primary: linear-gradient(135deg, #00c9ff 0%, #92fe9d 100%);
 * 
 * 3. Earthy Palette:
 *    --color-bg-primary: #1a1a1a;
 *    --gradient-primary: linear-gradient(135deg, #fa709a 0%, #fee140 100%);
 * 
 * LAYOUT ALTERNATES:
 * 
 * 1. Card Grid: Change services-grid to masonry layout
 * 2. Hero: Add parallax scrolling effect
 * 3. Navigation: Try a sidebar navigation on mobile
 * 4. Footer: Add newsletter subscription form
 * 
 * ANIMATION UPGRADES:
 * 
 * 1. Add scroll-triggered animations (AOS library or Intersection Observer)
 * 2. Parallax effects on hero section
 * 3. Stagger animations for service cards
 * 4. Smooth page transitions
 * 5. Micro-interactions on buttons and cards
 * 
 * DARK/LIGHT MODE TOGGLE:
 * 
 * Add a toggle button in navbar and create:
 * [data-theme="light"] {
 *   --color-bg-primary: #f8f9fa;
 *   --color-text-primary: #1a1a1a;
 *   ... (invert colors)
 * }
