## Recent change
2026-05-28: User requested that all green areas be cut out, each element saved as a separate transparent PNG, original motif shapes preserved, and clarity enhanced. The repository regenerated all 18 assets from source crops using source-preserved grayscale strokes/textures instead of pure-black fills, updated the extraction script and documentation, produced v04 `green_cut_clear_lines` package, removed the old v03 package, and pushed commit `1684e07`.
