Make a precise structural correction to this macOS app icon while preserving the same ivory porcelain rounded-square tile, soft upper-left lighting, centered composition and translucent jade-green glass material. The tool must be a recognisable open-ended mechanic's spanner, NOT A FORK. Correct the upper-left head: it has EXACTLY TWO short thick opposing jaws separated by ONE broad U-shaped open gap. Remove the extra middle tooth completely, leaving a single empty concave U-shaped opening between two jaws. No middle tooth, no third prong, no comb, no fork tines. The upper-left wrench head has a broad round outer silhouette and one open U-shaped notch. Preserve the long smooth diagonal jade glass handle and the single circular hanging hole at the lower-right end. One wrench only. Rounded sculptural glass, delicate transmission of jade color, bright pale tile, gentle shadow. Keep the whole object comfortably inside the tile. No text, no letters, no logos, no command symbol, no watermark, no other objects.
