What It Provides in WorldWeaver

WorldWeaver is organized into small modules that together cover the whole world-generation workflow:

• Biome APIs - registering biomes, attaching climate parameters and injecting them into the nether, end or overworld biome sources.
• Feature APIs - registering configured and placed worldgen features (plants, ores, surface decorations) with helper builders.
• Structure APIs - registering structures, structure sets and processors.
• Surface-rule APIs - attaching custom surface rules to biomes so they can shape their own terrain surface.
• Tag APIs - creating and populating block, item and biome tags from code.
• World preset and level-stem helpers - managing dimension setup and world presets.
• Datagen utilities - generating models, tags and other assets at build time.
• WunderLib - the bundled UI/layout toolkit used by the team's screens.

If you are not a mod developer, none of this is visible in game - the library simply has to be present so dependent mods can run.
