Opus 5.5 vs Sonnet 5.5: Dino Jelly cube

Build a single-file interactive 3D web page called "Dino Jelly" using Three.js (import from a CDN, no build step).

CONCEPT
A translucent, wobbly jelly cube floats in the middle of the page like a collectible diorama. Inside the top layer lives a tiny prehistoric island: a lush jungle of palms and giant ferns, a smoking volcano, a baby T-Rex, a long-neck brontosaurus, a few eggs in a nest and a fossil skull half buried in the sand. Below the island the cube shows cut-away soil layers (sand, clay, dark rock, glowing magma at the very bottom) like a cake slice.

LOOK
- Soft, warm off-white studio background, huge soft shadow under the cube, no harsh black.
- The jelly must feel real: transmission/refraction, thickness, subtle caustics, slight inner glow, glossy rim highlight, gentle subsurface colour.
- Editorial typography on the left: big italic serif title "Dino Jelly." with a one-line subtitle, small caps captions in the bottom corners.
- A minimal frosted control panel on the right, tiny type, 1px borders, lots of air.

MOTION
- The cube idles with a slow float and a continuous jelly wobble (spring-damped vertex deformation). Clicking/dragging the cube pokes it and the whole thing jiggles, the island inside lags behind slightly.
- Volcano emits smoke puffs and occasional lava bombs that splash into the jelly with ripples.
- The T-Rex blinks and roars every few seconds (head tilt + jelly ripple); the brontosaurus slowly turns its neck; palms sway.
- Camera: slow orbit, OrbitControls
