带风车和瀑布的秋日漂浮体素岛

Build an autumn floating voxel island scene that runs in the browser. Show a large central island of blocky earth with a dark rocky underside, covered in red, orange and golden trees, bushes and a wooden windmill whose sails turn slowly. Let a narrow waterfall spill from the edge into the air. Surround it with several smaller floating islands, each with a tree or small structure, and drifting purple voxel clouds against a soft pink and cream sky. Add falling leaves and tiny floating particles around the island. Use a camera that orbits slowly around the scene, with warm soft lighting and gentle shadows. Keep every object built from cubes with a consistent voxel size. Deliver one self-contained HTML file using Three.js with a small caption in the corner naming the scene. Done means the scene loops smoothly, the windmill rotates and the islands look balanced from every angle.
