《Semantic Pull: Word Family Grid》

Act as a Master Game Designer and Technical Architect specializing in immersive educational mechanics and high-fidelity 3D prototyping. Your task is to construct a detailed design specification and prototype blueprint for a 3D semantic classification game.

Game Title: 《Semantic Pull: Word Family Grid》

Core Objective: To create an engaging, tactile learning experience for English vocabulary acquisition through dynamic, physics-based semantic classification.

I. Game Mechanics & Interaction (The Core Loop):
Detail the precise physical interaction model. The environment must simulate a magnetic-like force field.

1. Environment Setup: The viewport is dominated by three distinct, glowing 3D conceptual zones (e.g., a Cube, a Cylinder, and a Torus) representing semantic categories (e.g., Animals, Fruits, Colors). These zones must serve as the primary attraction points.
2. Interactive Elements: Multiple floating crystal nodes (representing individual vocabulary words) drift dynamically within the space under a subtle, low-frequency noise algorithm.
3. User Input & Physics: The user interacts by dragging any crystal node. Upon release, the system must calculate the real-time distance and determine a magnetic attraction vector towards the nearest correctly aligned category zone.
4. Feedback Loop:
   • Success: If the crystal aligns with the correct zone, it must be absorbed via a smooth, visually satisfying Linear Interpolation (LERP) scaling animation, accompanied by a bright burst of light trails and a satisfying sonic cue.
   • Failure: If the crystal is misplaced, it must exhibit an elastic repulsion vector, snapping it back to its original position with a spring-like bounce, reinforcing the spatial relationship.

II. Visual Design & Aesthetic (The Style Guide):
The visual style must be a fusion of Retro-futuristic Cyberpunk aesthetics tailored for a youthful audience.

1. Lighting & Materials: Employ a high-contrast, dark background. All interactive elements (zones and crystals) must utilize highly emissive, translucent neon materials with strong volumetric lighting effects.
2. Depth & Detail: Incorporate holographic visual distortion effects within the crystals to emphasize their high-tech nature. Utilize dynamic parallax effects to enhance the sense of depth within the 3D space.
3. Color Palette: Dominated by deep blues, purples, magentas, and electric cyan/neon greens.

III. Technical Blueprint & Implementation Notes:
Specify the required technologies and the role of each component in achieving the desired immersion.

1. Primary Engine: Three.js (for 3D rendering, asset management, and shader implementation).
2. Animation & Physics: GSAP (specifically for non-linear magnetic spring and attraction interpolation) must govern all movement, attraction, and repulsion physics.
3. Interaction Precision: Raycaster must be used for high-precision 3D bounding box interaction detection between crystals and zones.

Desired Output: Provide a comprehensive design specification detailing the structure, interaction flow, aesthetic guidelines, and technical implementation strategy for developing this prototype. Focus on the interplay between the educational goal and the dynamic physics.
