Strata gain a dip, a slow seeded warp that bends and notches the beds, and a per-bed thickness and hardness jitter with ordered boundaries, so walls never invert. BoulderField gains an angularity parameter: elongated super-ellipse slabs with flat tops, sharp shoulders, random heading and tilt, footprint area preserved. Both sites are re-baked with the new settings; the coral heads stay rounded. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
