Animated voxel-art 3D story scene of an ice dragon freezing a lava castle

GOAL: Create a single self-contained HTML file using Three.js that renders an animated voxel-art 3D story scene, 14 seconds long: "Frost over Fire". MOTION: A black obsidian fire castle stands on a basalt rock in the middle of a lava lake: corner towers and a keep with burning braziers, glowing windows, red banners, a red-hot portcullis, lava falls pouring out of caves in the cliffs, glowing cracks in the rock and embers rising into a red, smoky sky. Story: an ice dragon (crystal spikes, glowing eyes, big membrane wings) flies in from the distance, leaving a snowy trail. Its frost breath hits a tower: ice spreads over the stone voxel by voxel, icicles grow and a lava fall freezes. The castle fights back with fireballs from the beacon on the keep; the dragon dodges and puts out the last one with its breath in a burst of steam. Then it sweeps low over the castle breathing frost: a freezing wave runs across the walls and the whole lava lake, the braziers go out in puffs of steam, the embers turn into snowflakes and the red sky becomes a starry night with an aurora. At the end the dragon rears up over the frozen castle and roars, breathing frost into the sky. Add soft shadows, glowing lava and luminous ice, particles for fire, frost, steam and snow, and a slow cinematic camera orbit. Make it as detailed and polished as possible.
