hbmspace:chunk_odds

Starts a structure in each chunk with a fixed chance.

Every chunk is a candidate; it starts the set's structure when a random draw seeded from the level seed plus salt and the chunk position is below frequency. /locate finds such structures. Vanilla placement fields such as exclusion_zone are ignored.
