/* =========================================================
   Datatech Solutions - styles.css (Cleaned + Fixed)
   Fix: Hero “jumping/fading” caused by duplicate @keyframes float.
   Change: Split animations into unique names:
     - hero-float for .hero-image (gentle translateY only)
     - particle-float for .particle (translate + opacity)
   Also: Removed duplicates + consolidated repeated blocks.
