Derived Play: Dovetail Prompt Fit

Create a single polished gallery image for a derived play concept titled Derived Play: Dovetail Prompt Fit. Show a compact tactile tabletop prototype in an open wooden tray, with interlocking harmless model blocks, dovetail sliders, soft mask pads, crop fences, finish swatches, tiny fictional output plaques, a foldout tolerance ribbon, and a wax scoring token. The game mechanism is prompt assembly by physical fit: readable labels should include Tenon Draft, Mortise Lock, Dowel Trade, Clamp Veto, Stamp Check, Finish Swap, Fence Crop, Square Match, and Wax Score. A piece scores only if it fits flush, the stamped word remains readable, three tiny fictional output plaques show the same invented object family from varied angles, and the wax token seals the tray after all source tags are fictional. Diagonal exploded-view macro photograph, warm maple and walnut, brass pins, frosted vellum, graphite tolerance marks, crisp engraved labels, no hands, no active cutting tools, all sample objects fictional and unbranded.
