Animated Isolate Motion GIF Effect

Isolate the black bat silhouette + white ECG line on its wing; remove background, triangle, border, "XI", sonar arcs, and banner text. Transparent background, alpha preserved, no white/checkerboard fill. Animate as a seamless looping GIF: wings flap continuously through a natural range of motion, ECG line stays fixed to wing surface, body/head mostly still with slight bob synced to flap. Smooth loop, no jump-cut, ~2-3 flaps/sec, transparency kept every frame.
