    -   `AnimationClip` - Individual animation management
    -   `AnimationClipFactory` - Animation creation with metadata parsing
    -   `StateHandler` - Abstract base for state implementations
    -   `StateFactory` - Dynamic state handler creation

-   **State Handlers:**
    -   `WaitStateHandler` - Idle state with quirk animations
    -   `ReactStateHandler` - User input response with emotion analysis
    -   `TypeStateHandler` - Typing state with emotional variations
    -   `SleepStateHandler` - Inactive state management

-   **Animation Loaders:**
    -   `AnimationLoader` - Abstract animation loading interface
    -   `GLTFAnimationLoader` - GLTF/GLB model animation loader

-   **Factories:**
    -   `OwenSystemFactory` - Main system assembly factory

### Features

-   **Animation System:**
    -   Support for Loop (L), Quirk (Q), Transition (T), and Nested animations
    -   Automatic metadata parsing from animation names
    -   Efficient animation caching and resource management
    -   Smooth transitions between states and emotions

-   **State Machine:**
    -   Four core states: Wait, React, Type, Sleep
    -   Emotional state transitions (Neutral, Angry, Shocked, Happy, Sad)
    -   Automatic inactivity detection and sleep transitions
    -   Message analysis for emotional response determination

-   **Developer Experience:**
    -   Comprehensive TypeScript type definitions
    -   JSDoc documentation for all public APIs
    -   Example implementations and demos
    -   ESLint configuration for code quality
    -   Vite development server setup

### Documentation
