1.0.0 Initial Release

• Initial release of spatial_card, a high-performance Flutter package for 3D tactile interactive cards.
• Multi-Plane Z-Parallax: Render arbitrary Flutter widgets on distinct elevation depth planes (SpatialLayer) with dynamic drop shadows.
• Physical Specular Lighting: Interactive glare and fresnel reflections reactive to touch coordinates and pointer hover.
• Holographic Chromatic Dispersion: Prismatic diffractive foil gradients that refract light across the surface.
• Built-in Material Presets:
  • SpatialMaterial.holographicFoil() (Iridescent collectible & gaming card sheen).
  • SpatialMaterial.brushedTitanium() (Apple Card-style metallic micro-grooves).
  • SpatialMaterial.frostedGlass() (Obsidian glass neobank & dark UI card).
  • SpatialMaterial.cyberNeon() (Cyberpunk glowing rim card).
  • SpatialMaterial.carbonFiber() (Diagonal woven carbon-fiber texture).
  • SpatialMaterial.goldFoil() (Polished warm metallic gold leaf).
• Interactive 3D Flip Card: SpatialFlipCard with seamless 180° double-sided rotation and continuous lighting.
• 3D Card Stack: SpatialCardStack with progressive depth scaling, defocus opacity, and swipe gestures.
• Lightweight Decorator: SpatialContainer for wrapping any arbitrary widget with 3D tilt and specular sheen.
• Tactile Dynamics: Spring snap-back damping, press-down depth depression, micro-haptics, and ambient idle drift breathing loop.
• 100% Pure Flutter: Zero heavy native ML models, zero native C++ build breakages, 120 FPS performance on Impeller and Skia across iOS, Android, Web, macOS, Windows, and Linux.
