Derived Play: Prism Split Draft

Create a single polished gallery image for a derived play concept titled Derived Play: Prism Split Draft. It should be a different artifact from the optical bench: show a compact cooperative tabletop game made from a triangular prism hub, removable beam cards, mirrored reference tokens, shutter masks, iris rings, focus cards, rail-stop gauges, diffraction tiles, fringe penalty chips, and three tiny focal-proof plaques. This is not a board grid, not a contact sheet, not a route map, not a chessboard, not an elevator queue, not a courtroom game, and not a music-box station. Gameplay mechanism: players draft one beam card into the prism hub, may split it once, must bounce exactly one reference token from a mirror, close one shutter mask to remove an off-brief detail, set one crop iris and one aspect rail stop, then place a caption focus card; they score only if the three focal-proof plaques preserve the same invented cloudstone lantern while the drift-fringe chips stay below the limit. Readable labels should include Beam Draft, Prism Split, Mirror Token, Shutter Mask, Iris Set, Rail Stop, Focus Card, Grating Tile, Fringe Penalty, and Focal Proof. Output format: crisp product photo of a harmless fictional optics drafting game with glass prism hub, brass rails, translucent cards, tiny light paths, no people, no hands, no logos, no real brands, no public figures, no copyrighted characters, no political content, no harmful instructions, no weapons, no gore, no sexual content, no living artist style imitation.
