Subtle Shimmer Across Geometric Logo

Do a shimmer moving smoothly from left to right across the entire subject. The shimmer should be subtle, with a narrow band of gentle light that enhances the existing highlights without changing the image composition, colours, or details. Do not add sparkles, glitter, particles, lens flares, glow bursts, twinkles, dust, floating effects, camera movement, zoom, distortion, or any other animation. Keep everything completely static except for the single left-to-right shimmer pass.
