Derived Play: Gear Drift Derby

Visible title: "Derived Play: Gear Drift Derby". A shallow circular transparent clockwork racing puzzle, 16:9 low oblique product photo. Interlocking brass gear lanes, removable tooth tokens, winding keys, balance-wheel gates, jewel checkpoints, timing clips, drift wedges, sealed score casebacks. Rim rules: Wind Claim, Crown Set, Tooth Trade, Fork Release, Jewel Read, Pendulum Return, Caseback Seal. Players choose a blank subject gear, set one crown context, trade one tooth to change detail density, pass the fork gate, read one invented jewel label, return to the timing mark, then seal the score. Make it tactile and playable, like a premium clockwork strategy toy, not a board grid, not cards, not pinball, not abacus, not a maze chip, not puppets, not paper folding, not a route map, not camera gear. Fictional, brand-free, person-free, rights-safe, nonpolitical, nonsexual, nonviolent. No real logos, no celebrities, no copyrighted characters, no watermark, no QR code.
