Use case: background-extraction. Edit target: the supplied pixel-art portrait of Priya. Remove ONLY the flat pale cream rectangular background and replace it with genuine fully transparent alpha. Keep the character artwork unchanged: exact same identity and face, deep-brown skin tone, round gold glasses, long dark braid, jade-green cardigan, cream blouse, red-brown book, hands, pose, proportions, crisp dark pixel outlines, ordered dithering, colors and pixel illustration style. Preserve the full original canvas framing and all foreground pixels and props. The cream blouse, whites of the eyes, glasses details and light book-page edges are FOREGROUND and must remain opaque; remove only the connected surrounding background and natural gaps outside the body/hair. Keep clean crisp pixel edges without a cream halo. Do not redraw, beautify, crop, enlarge, add shadows, add new objects or change expression. Output a true RGBA PNG with alpha transparency, not a checkerboard image or another flat color.
