Piece 1 (anchor run, no --sref): four candidates; #3 has the cleanest horizon and the terracotta sits exactly where the brief wants it. Upscaled, uploaded, URL saved.

Pieces 2–12 (with --sref anchor, --sw 250): each run returns four siblings in the same palette and block-colour language; the mountain silhouettes vary — a ridge, a twin peak, a low rolling range, a lake reflection — while the horizon line stays at the lower third in all of them.

Collection check (grid view): twelve tiles, same cream sky, same three colours, same weight. Two pieces (#7, #10) introduced a fourth colour; rerun those with --sw 300. Final set: 12 squares, 4K, no text, no signature, ready for a 3-mockup listing each.
