Extends StructurePlacement

Bedrock Edition's random spread placement: like Java's (one placement chunk per spacing x spacing region), but the offset comes from a Mersenne Twister seeded with the region coordinates, the world seed and the structure salt.

The seeding constants come from public Bedrock seed tools and are NOT verified against BDS yet (see STRUCTURES-PLAN.md): compare with /locate on a Bedrock Dedicated Server before relying on exact positions.
