Create an original science animation in Vivid Science style. Read STYLE.md. Use saturated complementary colour roles, smooth vector silhouettes, coloured shadow planes, expressive original characters, clear layers and purposeful scale changes. Establish the factual story and sources, generate the requested-language narration, then derive a shared frame timeline. Compose an original layered score, environment sound and action effects. Author new scenes; do not carry a previous subject or cast forward. Compare complete decoded reference and delivery sequences at every-frame metric coverage, inspect consecutive images and enlarged examples, watch motion and playback, and report listening coverage separately. Similarity features are diagnostics, not proof of artistic identity. Keep all production assets and evidence outside the library.
