Facebit - Layered Blendshape Animator

🔧 Features:

• Layer-Based Expression Blending: Assign expressions to layers (eyes, mouth, emotion, etc.) and blend them together with adjustable weights.
  
• Multi-Renderer Support: Animate blendshapes across multiple SkinnedMeshRenderer components (face, teeth, tongue, etc).
  
• Smooth Transitions: Expressions interpolate over time.
  
• Custom Editor UI: Dropdowns, sliders, foldouts, inline setup — all built-in with no dependencies.
  
• Preview Mode: Test expressions live in the Editor and restore original blendshape states when exiting.
  
• Unity Timeline Integration: Drop expressions into Timeline clips with full layer/expression control and transition durations.
