restore-blocky-sprite-to-20x18 met unchanged explicit

Restore a 1254 x 1254 AI-generated slime drawn in 39.7 px blocks to the hand-given 20 x 18 logical grid, keeping the single-cell eye highlight and the one-cell-thick mouth line intact. Reconstruction error alone also accepts a roughly 5x finer reading of the same image, so this output records which of the two scales is the intended one.
