## Loader differences

Recipe conditions and custom ingredients use the loader keys documented for NTM. On NeoForge, `data/leafia/neoforge/biome_modifier/add/ore_coal_oil.json` and `sellacity_roads.json` add Cursed features to `#minecraft:is_overworld` biomes; override or disable them as NeoForge biome modifiers. Fabric adds the same features in code.
