Create ONE landscape 3:2 storyboard image with exactly SIX equal panels, 2 columns and 3 rows, reading row-wise. Reference image establishes exact character, materials, palette and props; preserve them. Art direction translucent frosted glass miniature animation, seafoam aqua clear amber, delicate caustics and studio macro photography. Design a small amber glass seahorse post carrier with a blue glass satchel, a clear glass bottle containing one rolled ivory letter, underwater glass reef. No words, numbers, captions, lettering. Narrow white gutters. Strict state chronology, do not leak final state into early panels. Panels: 1: Sealed letter bottle stuck between reef branches, seahorse approaches. 2: Seahorse curls tail around bottle, neck remains trapped. 3: Bottle now free, seahorse holds it with tail, no broken glass. 4: Seahorse shelters behind reef with same sealed bottle during a wave. 5: Seahorse inserts sealed bottle into open clam-shaped mailbox. 6: Small glass crab recipient emerges beside mailbox and touches delivered bottle.
