Domino Chain Builder

Create a 3D domino chain builder using Three.js. Players click-drag to place ivory dominoes with pip dots and aim their fall direction, and can also place red balls that interact with the chain. Include an eraser tool, rotation controls with keyboard shortcuts (Q/E), and a physics simulation triggered by clicking a domino to push it. Add a slide-out physics panel with gravity presets for Moon, Mars, Earth, and Jupiter, plus sliders for push force, friction, bounciness, and time scale. Use a dark workspace aesthetic with warm amber accents, frosted-glass toolbar, shadow-mapped lighting, and orbit camera controls.
