/* ═══════════════════════════════════════════════════════════════
   wit-immersive.css — Wave 13 Immersive Visual Design System
   ═══════════════════════════════════════════════════════════════
   
   Holographic & Glassmorphism Aesthetics:
   - Multi-layer glass with dynamic blur, neon outlines, depth shadows
   - Holographic shimmer and scan-line effects
   - Fluid glow animations for interactive elements
   
   Micro-Mini Interactions:
   - Subtle haptic-like visual feedback (scale, glow, ripple)
   - Touch/click response animations (50-150ms)
   - Status-driven glow pulses
   
   Spatial UI foundations:
   - Floating element system with depth layers (z-space)
   - Perspective transforms for cinematic depth
   - AR overlay container with camera backdrop support
   
   All variables cascade from tenant theme CSS variables (--wit-*).
   Works with all 7 design kits: Futuristic, Glass, Neon, Minimal,
   Nature, Ocean, Corporate.
