How to use
1. Drop in a high‑res brick photo (2 px/mm or better for real detail).
2. Set the wall size you want. Panels are cut to fit the 205×215 bed.
3. Tune black/white/gamma until mortar reads dark and brick faces read bright.
4. Check the 2D map — seam lines should land on mortar joints.
5. Export the ZIP, print, assemble by the numbers engraved on the back.
