Create a 20-second cut-paper explainer on a warm sand background. Three wavy paper hills in shades of rust slide up from the bottom with soft shadows and drift slowly sideways, and a pale paper sun rises. A cream paper banner drops in, slightly tilted, reading "How compost feeds a city". Then three cream paper cards slide in from the right one at a time, each with a rust cut-paper badge — a circle "1", a triangle "2", a rotated square "3" — and a step: "Collect — Kitchen scraps go in the green bin", "Break down", "Grow". It ends with "Small scraps, big loop." and "Explained in 20 seconds".
