Random Layers
Random Layers transforms world generation into clean, deterministic strata: each Y-level is assigned a single block type across the world. The block for each height is chosen from a valid pool using your world seed and dimension, so results are chaotic but fully repeatable.

- Replaces terrain and generated structure blocks by Y-level
- Supports vanilla + modded blocks in the layer pool
- Configurable blacklist support:
- Namespace blacklist (example: create)
