Derived Play: Cast Brush Rally

Prompt text

Create one polished public-gallery image titled "Derived Play: Cast Brush Rally". This is a derived playable mode from Prompt Excavation Block, but it must look like a different rules object: a cooperative timed fossil-casting tabletop challenge, not a museum specimen drawer and not a static excavation display. Do not make a 2x3 board, contact sheet, card spread, grid poster, sand tray, ice-core rack, route map, library cabinet, elevator puzzle, optical game, toy lock, neon path, chessboard, courtroom game, music box, proof press, loom, patchbay, planetarium, or pinball table.

Scene: a low oblique product photograph of an oval plaster casting arena on a neutral studio table. The arena has a raised central mold shaped like a fictional leaf-sprocket, removable soft brush tokens, colored sediment wedges, rubber void plugs, tiny label pin flags, foam scale hoops, three cast trays, a safe-source crate, and a small non-electronic turn timer. No people, no hands.

Playable rules shown through objects: players rotate the arena one notch per turn, draw one Sediment Wedge, place one Brush Token to reveal a clue, insert one Void Plug to remove an unwanted motif, pin exactly one readable Label Flag, fit a Scale Hoop without covering the fossil, and pour a harmless dry casting token into one of three Cast Trays. They score only if all cast trays preserve the same invented leaf-sprocket and the source crate stays sealed.

Readable short labels on components: Wedge Draw, Brush Token, Void Plug, Label Flag, Scale Hoop, Cast Tray, Timer Notch, Source Seal, Rally Score. Visual language: premium tactile tabletop game prototype, chalky plaster, rubber plugs, walnut rim, teal/yellow/rust sediment wedges, ivory flags, graphite labels, crisp shadows, playful but sophisticated. Everything is fictional, unbranded, rights-safe, non-political, non-adult, non-graphic, and harmless. Exclude real marks, public figures, restricted characters, imitation of living artists, unsafe instructions, weapons, explicit material, graphic harm, and watermarks.
