熔岩流淌、船只逃离的交互式火山岛

Build an interactive volcanic island in the browser as one self-contained web page. A green island with trees and small huts sits in the sea, with a volcano in the middle. The user can trigger an eruption: glowing lava runs down the slopes, smoke and embers rise from the crater, and the sky darkens. Small boats around the island notice the eruption and sail away from it. Include a simple on-screen control for erupting and one for resetting the scene, plus orbit-style camera movement so the island can be viewed from different angles. Use a warm orange lava glow against dark smoke and calm blue water. Keep the scene light enough to run smoothly on an ordinary laptop. It is done when the eruption, flowing lava and fleeing boats all work and the scene can be reset.
