Use case: background-extraction. Edit target: the supplied pixel-art portrait. Remove ONLY the flat pale cream rectangular background and replace it with genuine fully transparent alpha. Keep all character artwork unchanged: exact same identity, face, skin tones, hair, clothing, props, hands, pose, proportions, framing, crisp dark pixel outlines, ordered dithering and palette. Preserve the full original canvas framing and foreground; light foreground details must remain opaque. Remove only surrounding background and natural gaps outside body/hair; clean crisp pixel edges without a cream halo. Do not redraw, beautify, crop, enlarge, add shadows/new objects or change expression. Output a true RGBA PNG with alpha, not a checkerboard image or flat color. Preserve Claire's older face, blue eyes, strawberry-blond and silver curls, cream shirt with red/pink flowers and green foliage, olive-green garden overalls, hanging gardening gloves, brown flowerpot with green seedling, hands and gentle smile. The cream floral shirt and silver hair highlights are FOREGROUND and stay opaque.
