Sprite-Pipeline cleans AI frames into sheets

This is the unglamorous layer AI sprite workflows actually need: not better generation, but deterministic cleanup, alignment, and packing that make assets shippable.

• –The repo positions the tool as a reusable pipeline, not a one-off generator, which matters when teams need repeatable output across many animations
• –Foreground extraction, light correction, PSD building, and spritesheet packing target the real failure modes in AI art pipelines: messy edges, perspective drift, and inconsistent frame structure
• –The `256 x 256` strip workflow suggests a production-minded default that fits common game asset conventions rather than novelty demos
• –For AI game dev, this is infrastructure value, not model hype: it sits between image generation and engine import, where most quality work actually happens
