Turn a text prompt into a petdex-spec spritesheet (8×9 grid of 192×208
cells), grounded so every animation row stays the same creature:
- orchestrate: base drafts (distinct variation nudges) → per-row grounded
generation → atlas compose; one image call per row, rows fan out in parallel.
- atlas: frame-perfect registration in normalize_cells — 1-D cross-correlation
of each frame's column-mass profile locks the body (robust to limbs/cape),
one shared per-state scale, bottom-anchored; plus alpha-hole repair, gutter
severing, and interior-seeded chroma-pocket clearing.
- prompts: pixel-art-by-default style hints + registration constraints.
- store: local pet write (register_local_pet), slugify/unique_slug,
export_pet, slug-realigning rename_pet, createdBy provenance.
