Лоукост-замок на парящем острове с днём и ночью на Three.js

Build an interactive low-poly 3D castle scene with Three.js. Place a stone castle with several round and square towers, red pointed roofs, a gate with an arched door, battlements and a flag on a small floating grass island with rocky underside, pine trees and a wooden bridge. Add drifting clouds in a light blue sky. Include a day and night toggle: at night the sky turns deep navy with stars and a moon, and the windows and gate glow warm orange. Let the user orbit and zoom around the castle with the mouse, with a small on-screen hint about the controls. Use flat shading and a simple, clean palette. Deliver one self-contained web project. Done means smooth camera control and a clear visual change between day and night.
