## What it is
A cross-engine tool written in Rust for losslessly compressing sprite textures by splitting them into units, discarding identical regions, and baking unique units into atlas textures for runtime reconstruction. It ships as a standalone CLI, a Rust crate with C ABI, and first-party Unity and Godot plugins.

## Use cases
- compress character sprite sheets for a visual novel
- reduce game build size by deduplicating identical texture regions
- generate sprite atlases from PNG or WEBP textures
- bake diced sprite atlases for Unity or Godot
- losslessly shrink textures that share most of their pixels

## When to choose
- your game has many sprites with large identical areas, like character emotion variants
- you need engine-agnostic atlas baking usable from Unity, Godot, or custom engines
- you want lossless texture compression with a simple CLI workflow

## When to avoid
- your sprites have little to no overlapping content, so savings would be minimal
- you need lossy texture compression or GPU-native texture formats like BC7
- you need runtime-only compression without a preprocessing build step
