Derived Play: Grit Spiral Auction

Create one polished public-gallery image titled "Derived Play: Grit Spiral Auction".

It is derived from Prompt Tumbler but becomes a different playable object: a risk-bidding spiral sieve game made from loose pebble tokens, cloth grit pouches, and rotating sieve arcs, not the same tumbler machine.

Output format: one vertical 3:4 overhead-oblique tabletop product photograph of an oval slate play mat with a raised brass spiral sieve track, eight turquoise crescent-seed pebble tokens, five felt grit pouches, two amber wax chips, a rotating loupe gate, three quiet-sieve shutters, a caption cloth banner, and a small score trough. No people, no hands, no logos, no real mineral brands, no real industrial procedure.

Play rules shown through objects: players secretly bid one Grit Pouch, move a Crescent Token through the Spiral Sieve, spend one Wax Chip to protect the marker, rotate the Loupe Gate to change the view, close a Quiet Shutter to remove decoys, write one two-word Caption Cloth, and score only if the same turquoise crescent seed with two ivory dots and one graphite notch reaches the Proof Trough without losing its mark.

Short visible labels: Grit Bid, Spiral Sieve, Wax Guard, Loupe Gate, Quiet Shutter, Caption Cloth, Proof Trough, Auction Score. Visual language: premium tactile tabletop prototype, oval slate mat, brass spiral, amber wax chips, turquoise crescent seed, ivory dots, graphite notch, soft felt pouches, crisp readable labels, refined and playful. Fictional, original, unbranded, harmless, rights-safe, non-political, non-adult, and non-graphic. Avoid public figures, real brands, celebrity likenesses, copyrighted characters, dangerous instructions, weapons, gore, and living-artist style imitation.
