Use case: background-extraction. EDIT TARGET: the supplied Akiko portrait. Change ONLY the pale cream rectangular background to genuine transparent alpha. Preserve the entire character exactly: Black Japanese adult teacher's face and rich brown skin tones, short coily bob, gold heart hairclip, ivory blouse, mustard cardigan, blue notebook, hands, pose, framing, clothing folds, crisp pixel outlines and ordered-dither texture. Do not redraw, reimagine, beautify, recolor, mirror, resize or reposition her. Keep the original1122x1402canvas and same character scale. The ivory blouse and all light-colored clothing must remain fully opaque; remove only background areas outside the character and through true exterior gaps. Retain clean crisp pixel edges with no cream halo. Transparent PNG cutout, not a white/cream backdrop and not a drawn checkerboard. No shadow, scene, text, border, label or watermark.
