Poetic 15-Second Shadow Sapling Video Prompt

15-second poetic experiment in a bare courtyard. A child approaches a tiny sapling with pruning scissors. Its shadow is impossibly large: a mature tree filled with moving bird silhouettes. 0–5s: The child raises the scissors toward one small branch. 5–10s: Before the blades close, the corresponding shadow branch falls away. Its birds scatter across the wall. The child freezes. 10–15s: The child lowers the scissors and waters the sapling. The missing shadow branch grows back. One bird lifts off the wall as a real bird and lands on the tiny tree. Locked composition, clear sunlight, precise shadow animation. No text.
