About

A new superflat-based world type with hilly ocean terrain (Y40-Y62), abundant shipwrecks on the surface, shipwreck chests containing 35% apples and 45% diamonds, and underground strongholds built entirely from mossy stone bricks. Implemented via a custom chunk generator with simplex noise, loot table overrides, mixin-based block replacement for strongholds, and datapack world preset registration.
