Create a concise educational sequence explaining how a fictionalized temperate salt marsh stores carbon. Follow the verified relationship in Image 1 without copying its graphic style or labels. Use Video 1 only for mud, cordgrass, shallow water, and natural wind movement; do not imply that the footage proves a specific numerical claim.

0–4 seconds: eye-level field view as the tide moves gently between grass stems. 4–9 seconds: camera passes below the waterline in a clean visual transition, revealing roots and suspended organic particles settling into layered sediment. 9–13 seconds: simplify the scene into an original cutaway model showing plant growth above and gradual burial below. 13–15 seconds: return to the real marsh view with empty lower-third space.

Narration intent: plain language, one idea per sentence, no unverified percentages or universal claims. Sound intent: soft wind, water movement, one restrained transition tone. Preserve correct flow direction, root continuity, scale cues, and species count. Avoid false time-lapse speed, invented data, labels generated inside the video, disaster imagery, copied infographics, or watermark.
