## Recent change
2026-05-28: User approved the other motifs and flagged only five missing-edge items: `LZP-013` missing left side, `LZP-012`/`LZP-011`/`LZP-010` missing bottom, and `LZP-009` requiring correction. The repository only re-cut these five assets: `LZP-013` was expanded leftward to restore the left-side beast-head detail; `LZP-010`/`LZP-011`/`LZP-012` were expanded downward to restore bottom outlines; `LZP-009` was tightened to reduce guide fragments. Generated v05 `missing_edge_completion` package and pushed commit `672c68d`.
