//! Core data structures representing the voxel world.

//! The module is split by concept: [`BlockId`] material handles, the [`Chunk`] storage forms, chunk-space coordinates in [`ChunkPos`], and precision-safe entity positions in [`EntityPos`]. Each lives in its own submodule and is re-exported here so callers continue to refer to `shared::world::<Type>` regardless of the internal layout.
