Derived Play: Checkmate Prompt Relay

Create a single polished gallery image for a derived play concept titled Derived Play: Checkmate Prompt Relay. It should be a different artifact from the workstation: show a fictional head-to-head tabletop relay game on a long tournament table with two compact chess clocks, a narrow move-track board, clause-piece tiles, sealed crop envelopes, reference-knight cards, mask-pin clips, style-gambit coins, safety-resign tokens, and a final checkmate display stand holding three fictional image-result cards. The gameplay mechanism is timed prompt relay: players alternate placing one clause tile as a legal chess move, may capture one off-brief detail into a tray, can castle context once, must pin exactly one masked region, and win only when the three result cards show the same invented object family across different crops. Readable labels should include Clock Bid, Clause Move, Capture Detail, Castle Context, Knight Reference, Pin Mask, Gambit Coin, Resign Token, Mate Proof, and Score Flag. Premium macro photography, ivory felt, charcoal tiles, brass timers, red and blue notation pencils, crisp readable labels, no hands, no logos, no real brands, no real people, no political content, no dangerous instructions, no gore, no sexual content, no living artist style imitation.
