   SALESFLOW SUPPORT — Premium Background Motion (Unique Design)
   Features:
   • Layered aurora ribbons (conic & radial gradients)
   • Parallax star dust (multi-layer drift + twinkle)
   • Neon perspective grid floor (subtle)
   • Floating glass orbs with soft glow trails
   • Prefers-reduced-motion safe
   Notes:
   - No HTML changes needed. Uses existing elements:
     .background-container, .gradient-bg, .floating-shapes, .grid-pattern
   - Works in dark/light; tuned for dark.
