桜の寺院と昼夜切り替えがある空飛ぶボクセル島

Build a single-page interactive 3D scene of a floating voxel island in the browser, using Three.js and delivered as one self-contained HTML file. The island carries a Japanese-style temple with tiered green roofs, a red pagoda, pink cherry-blossom trees, pine trees and a waterfall that spills off the edge into the clouds. Use a soft pastel daytime palette on a pale background, with a small sun made of pixels. Add a day/night toggle: at night the sky turns deep navy, blossoms turn lilac, lanterns and windows glow warm, and a pixel moon appears. Overlay a minimal editorial UI: a serif title, a short tagline that changes with the time of day, and a bottom bar with camera presets for the whole island, the temple and the falls. Support drag to orbit and scroll to zoom, with smooth camera transitions between presets. Done when the island reads clearly from every angle, the toggle fades lighting smoothly, and the camera presets glide to their targets.
