The sky-island mechanic — in 3D

What you're looking at. A slowly-rotating token at the base. From one point on it, a translucent energy cone broadcasts upward — more light than solid, an ice-cream-cone of energy. A small grassy island floats at the cone's tip. The coin docks centre-on-axis: its middle touches the cone tip, so every slice stays reachable around the rim.

Sliver = the resting state. By default the coin hangs edge-on below the island — you just see a sliver in the same perspective. Tap it and it surfaces: swings face-on up to the tip. That's the two states here — Surfaced and Sliver.
