Do not merely copy, re-encode, or return the source image unchanged.

Add a clearly visible but small graphite-and-watercolour illustration only inside this rectangle:

x=3200–3650, y=900–1300 on the 3840×2160 canvas.

This is the far-right middle area; do not touch the centre, which is reserved for Adam’s signature.

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

“Shelter is something we make for each other.”

Before submitting, compare the final image against the source pixel-by-pixel. The changed-pixel bounding box must be non-empty and must stay within the stated rectangle. If there is no genuine pixel change, do not submit. Preserve every pixel outside that rectangle exactly. Return the full 3840×2160 PNG and report the exact changed-pixel bounding box and final SHA-256.
