Use case: background-extraction. EDIT TARGET: the supplied naomi portrait. Change ONLY the pale cream rectangular background to genuine transparent alpha. Preserve Naomi's exact adult East Asian Japanese face, skin tone, long black ponytail, rectangular glasses, burgundy knitted vest, light-gray collared blouse, clipboard, hand positions and gentle calm expression. Preserve the same framing, clothing folds, crisp pixel outlines and ordered-dither texture. Do not redraw, reimagine, beautify, recolor, mirror, resize or reposition the character. Keep the original1122x1402canvas and same character scale. Every character pixel including all white/light-gray clothing and props must remain opaque; remove only exterior background and 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 scene, drop shadow, text, border, label or watermark.
