Modified Biome Source

Calls something that is on Kiln's roadmap. Parts of it may already run.

Evidence

Ran on Kiln's test stand (2026-11-04): ModifiedBiomeSourceFabric did not start: java.lang.NoSuchFieldError: Class net.minecraft.core.registries.Registries does not have member field 'net.minecraft.resources.ResourceKey BIOME_SOURCE'.

In the author's words
