Create a mythical floating island for Minecraft with an exact size of 160x160 blocks. The island must be centered on a 2x2 core (blocks 79–80 / 79–80) to ensure perfect circular symmetry. The top surface should be mostly flat and circular, designed as a plateau suitable for building. Design the island with the following clear radial structure: - Central sacred area: perfectly flat, radius ~14 blocks, reserved for a monumental structure (no buildings yet). - Surrounding open buffer ring to emphasize scale and mythic importance. - Outer plateau areas suitable for future functional and decorative builds. - Edge zones intentionally left open for future expansion, bridges, or additional floating islands. The island edges should feature rugged cliffs, overhangs, and erosion. Add waterfalls at
