Derived Play: Buoy Chain Regatta

Create one polished public-gallery image titled "Derived Play: Buoy Chain Regatta".

This is a derived playable mode from Prompt Buoy Chain, but it must look like a different rules object: a cooperative floating-token regatta played in a circular tabletop water arena, not the same panoramic calibration tray, not a navigation chart, not a boat race, not real marine equipment, not a 2x3 grid, not cards, not a contact sheet, not a rectangular board game, not a poster, not a toy latch, not a fossil drawer, not a wardrobe carousel, not a library cabinet, not a terrain model, not a weather station, not a kite tunnel, not a patchbay.

Output format: one square 1:1 overhead product photograph of a round shallow ceramic basin filled with clear water. Inside the basin are twelve floating modular buoys, three soft reef blockers, tiny washable caption pennants, translucent current rings, a turn dial clipped to the rim, and four proof coves around the edge. The only subject motif is an invented teal spiral shell with two square notches, repeated on safe foam tokens. No people, no hands, no real places, no boats, no animals.

Playable rules shown through objects: players take turns flicking a small current ring, then must move one buoy without breaking the cotton-cord chain. Each round they place an Anchor Token, rotate a Current Ring, slide a Drift Ghost, swap one Tide Edit buoy, park one Reef Blocker, clip one Caption Pennant, spend a Lantern Charge, and check that the teal notched spiral shell reaches the correct Proof Cove. A score only counts when the subject is still recognizable, the caption pennant is readable, the reef blocker excludes one unwanted motif, and the final proof cove repeats the same shell.

Readable short labels on components: Anchor Token, Current Ring, Drift Ghost, Tide Edit, Reef Blocker, Caption Pennant, Lantern Charge, Proof Cove, Chain Score. Visual language: premium tactile tabletop prototype, round ivory ceramic basin, clear rippling water, sea-glass teal, coral red, pearl white, graphite labels, small warm waterproof LEDs, crisp overhead shadows, playful but sophisticated. Everything is fictional, original, unbranded, rights-safe, non-political, harmless, non-adult, non-graphic. Avoid real brands, logos, public figures, celebrity likenesses, copyrighted characters, living-artist style imitation, weapons, dangerous procedures, gore, nudity, and watermark.
