Opus 5.5 builds an orbitable castle above the clouds in Three.js

Build one self-contained, real-time Three.js PBR web experience titled: CASTLE ABOVE CLOUDS

Subtitle lockup: A DREAM IN THE SKY · REBUILT
Hero line, large, two weights: Above the clouds, / there lives a castle.
Small supporting line under it: Drift slowly around eaves and towers, timber walkways and floating cottages. Moonlight skims the stone walls, and warm lamps come on in rooms where people live.

This is not a still. It is a screen-recordable product shot of a live scene. Mouse orbit, scroll zoom, slow auto-orbit when idle. Hold 60fps. Pixel ratio capped at 2.

WORLD
Night sky, deep blue-black, not pure black. Large pale moon, soft clouds at several depths, a few small stars. Cloud layer sits around the islands, not below the whole world. Faint breeze moves clouds and tiny pennants.
A cluster of floating rock islands. Undersides are dark, chunky, slightly mossy rock with hanging roots and a few dangling lanterns. Tops are lived-on ground: grass patches, stone paths, wooden decks.

HERO ISLAND
One large central castle-town, white plaster walls, warm stone base, red conical tower roofs, small yellow flags on the peaks.
Readable architecture, not a blob:
- main keep with a tall red spire
- attached round tower with slit windows
- lower wing with a green roof and open balcony
- wooden external stairs and a wraparound deck
- string lights along railings
- dozens of individual warm windows, some brighter, some dim, a few flickering
- a small market stall / awning on the lower terrace
- chimney, gutters, shutters, flower boxes if cheap
Scale is toy-like but materials are serious. Close orbit must not fall apart.

SATELLITE ISLANDS
At least six smaller floating islets at different heights and distances:
- one with a red-roof cottage and a chimney
- one with a white house and a warm porch lamp
- one almost empty rock with a single lantern
- one with a tiny tower and a flag
- two mid-size hamlets linked visually to the castle by implied paths, not a rigid grid
Each has its own rock underside. They bob very slightly, out of phase. No identical clones.

LIGHTING AND MATERIALS
Real-time PBR, stylized, not Unreal photoreal and not flat toon.
- Moon as key, cool, soft shadows
- Window and lantern emissive as practicals, warm 2200–2700K, bloom only on lights
- Stone slightly rough, plaster matte, roof tiles with a soft specular, wood with grain
- Rock undersides darker and rougher than the town
- A little atmospheric fog so far islands desaturate
- No harsh studio three-point. The moon path and window glow are the picture.

CAMERA
Start three-quarter above the castle, moon behind the towers.
Then a slow orbit: drop to deck level so string lights and windows read, slide past a satellite cottage, rise again to a high aerial of the whole cluster, return.
User can interrupt with drag and scroll at any time. Ease, no jitter.

UI
Editorial, dark glass, low chrome. Do not cover the castle. Left copy stays readable over sky. Right telemetry stays small. Cursor is a normal pointer; hovering a building can brighten its windows a touch, nothing else.

DO NOT
- Make one island with a castle texture
- Use a skybox city
- Add characters, combat, inventory, or a loading fantasy novel
- Go full Ghibli flat color or full photogrammetry
- Fake the float with a static render

Taste: a rebuilt dream you can orbit. Someone should be able to screen-record any second and it still looks like the product shot.
