《Syntactic Stack: Kinetic Grammar》

I want you to act as a Top-Tier Graphics and Interaction Engineer. Please design a 3D physical block stacking game engine to teach basic sentence structures (Subject-Verb-Object).

Game Name: 《Syntactic Stack: Kinetic Grammar》.

Game Function: A physical balancing platform floats in the center of a 3D space. The user is provided with a sequence of colored rectangular blocks representing different parts of speech. Clicking the screen drops a block from a set height onto the platform. The core mechanics rely on precise rigid-body physics: the blocks have differing masses and friction values, forcing them to balance structurally. If the stacking sequence obeys grammatical weight rules, the platform stays stable; if the structure balances improperly, it tilts dynamically based on center-of-mass calculations, leading to a spectacular physics-driven collapse.

Design Style: Bauhaus geometric aesthetic. Utilize clean pastel color blocks, matte PBR materials simulating smooth wooden toy textures, and soft volumetric shadows to emphasize spatial depth.

Technologies Used: Three.js for visual rendering, Ammo.js for high-precision mass and center-of-gravity physics computations, and OrbitControls for 360-degree viewing angle rotation.
