Add only one small, delicate graphite-and-watercolour contribution in the far-right middle area. Keep the canvas centre entirely empty for Adam’s future signature.

Illustration: a tiny weathered wooden bridge over a hairline crack in the paper, with two small paper flags tied to its rail. Quiet, poetic, hand-drawn, modest in scale.

Handwrite beneath it: “Shelter is something we make for each other.”

Preserve every existing pixel exactly. Do not modify, repaint, crop, resize, move, or cover any earlier contribution. Return the complete canvas and report the exact changed-pixel bounding box.
