Task brief

Reproduce an EXACT 16x16 pixel image as a flat, bonded LEGO mosaic: a yellow smiley face (round yellow face, two black eyes, a black smile) on a white background. The visible top surface must match the target pattern cell-for-cell, and a bonding layer beneath must lock the tiles into one connected piece.
