Visible Grid Pixel Mosaic (Style-Only, Image-Conditioned)

Re-render this image as a pixel mosaic of uniformly sized square color cells, each separated by a fine dark seam so the grid remains evident even in flat fields. Translate the source into flat mineral colors: chalk white, sandstone, slate blue, oxidized copper, terracotta, and ink. Place cells by hand in broad neighborhoods that trace the existing silhouette and light, with stepped edges instead of curves or antialiasing. Keep cell sizes identical across foreground and background, using contrast rather than scale to establish focus. Let selected cells have slight matte color variation like individually chosen tesserae, but keep their faces square and planar, never broken or irregular. Invoke the geometry of modernist grid studies and twentieth-century tiled murals, not a photograph of an installed wall. Treat the seam as a dark line one small fraction of a cell wide; if too thick, the source disappears behind the lattice. Preserve broad uninterrupted patches of the lightest or darkest color to keep the composition calm. Do not invent ornamental motifs or rearrange the subject into a new emblem. The image should be readable first as the original scene, then as an accumulation of discrete decisions. Avoid glossy tile reflections, softened edges, gradients, and random speckling. Leave a calm, uncluttered band of negative space along the top or bottom edge where a title could sit. Strictly no on-canvas text, no legible lettering, no signature, no watermark, no logos. Preserve the subject, pose, and composition of the source image exactly, change only the medium and rendering. Aspect ratio matches source.
