Steampunk Diorama of Obsolete Inventions as Edible Pastries

Steampunk diorama of obsolete 19th-century devices rebuilt as functional (but non-working) pastries with edible engineering. Pantelegraph (pre-telephone image transmitter) = layered puff pastry with jam "ink reservoirs" and spun sugar wires; Mechanical Turk chess automaton = marzipan figure with visible clockwork gears of crystallized ginger; Victorian hair receiver = spun sugar dome collecting "hair" strands of black sesame. Style: brass-toned lighting, exploded-view diagram floating beside each device showing pastry engineering layers, inventor's blueprint fragments as sugar paper. Viral hook: Obscure history meets whimsical engineering—triggers "I never knew this existed" shares.
