Create a 600 by 600, two-second promotional badge. Use a purple 12-point star with a pale inner circle, grouped at the center. Scale the group from 60 percent to 110 percent at 0.35 seconds and settle at 100 percent at 0.6 seconds. Fade it in. Add two small green diamond sparkles at opposite corners, with staggered opacity entrances. Hold the final state. Keep any offer or price outside the animation; do not invent a discount. Export the editable project.
