A magnificent brass-and-copper airship prepares for departure from a Victorian-era docking tower. Steam billows from its engines as ground crew in goggles and leather aprons cast off the mooring lines. Gears and pistons move in hypnotic synchronization. The ship's enormous propeller begins to turn, catching the golden sunset. Canvas wings unfurl with mechanical precision. Camera: Low angle looking up at the ship, then rising alongside as it ascends. Lighting: Golden hour with steam diffusion and brass reflections. Style: Detailed steampunk aesthetic, warm metallic color palette. Duration: 10 seconds.
