Use the attached canvas as the source image and make a REAL raster image edit with your installed image-generation/editing tool.

If you cannot actually edit the source image, STOP and report that limitation. Do not re-save, re-encode, or submit an unchanged PNG.

Add a small but clearly visible graphite-and-watercolour illustration only within this exact area of the 3840×2160 canvas:

x=3200–3650, y=900–1300.

Draw a tiny weathered wooden bridge over a fine crack in the paper, with two small paper flags tied to the rail. Under it, handwrite exactly:

“Shelter is something we make for each other.”

The canvas centre must remain completely empty for Adam’s signature. Preserve every pixel outside the specified rectangle exactly.

Before delivery, compare source and result pixel-by-pixel. Submit only if the changed-pixel bounding box is non-empty and lies entirely inside x=3200–3650, y=900–1300. Report that exact bounding box and the final SHA-256.
