Built-in imagegen edit mode, opaque white background. Edit target: user-provided c8602423c802de3aa155651031f63c35.jpg. Resized to exactly 684x300; normalized to grayscale and near-white background cleaned to pure white.

Use case: precise-object-edit. Make a 684x300 e-ink reader banner (aspect ratio 2.28:1). Replace only the gray textured background with clean solid white, including the gaps around the hand and body. Preserve the original thoughtful ape facing right, its face, fur, ear, hand, fingers and pose. Retain all the animal visible in the original photograph: head, hand, forearm and visible torso. Do not crop any more of it or invent a full body beyond the original. Scale proportionally to fit the banner height, subject at left, generous white space at right. Grayscale photograph, opaque white background. No text, borders or watermarks.
