Animated Spritesheets

Turn a character into a packed, engine-loadable spritesheet by generating one labeled pose-board image — a grid of the same character in the frames of an action — then recovering/slicing it. This is the image-generation method.

Why image generation, not image-to-video. One generation per action keeps identity consistent (cloak/face/weapon stay the same across frames); video morphs the character mid-clip. Trade-off: fewer frames (a model reliably lays out ~4–12 grid cells, not a long strip), so motion is choppier — per-frame pose labels + pixel-snapping make the few frames count.

The happy path

You are an agent. All scripts run with node <script> — no Python, no uv, and nothing to install: each imports a bundled, dependency-free scripts/_lib/.
