Cyberpunk Butterfly in a Bomb Shelter

A ultra-detailed cyberpunk butterfly inside a cramped bomb shelter. Riveted steel walls, peeling concrete, ventilation ducts, and flickering neon tubes casting cyan and magenta light. Emergency signage in garbled glyphs, rusted bunk beds, ration crates, and gas masks on hooks with tangled cables overhead. A chrome-coated butterfly with biomechanical wings, segmented metallic chitin, circuit patterns, and micro-LEDs along the wing edges; wings resemble stained glass with glowing electric veins in cyan and magenta. The butterfly's body is sleek titanium with tiny antennae sensors. The scene is moody and cinematic, with dust motes, rain streaks on a small vent, and a distant ruined city visible through a small window. High-contrast lighting, futuristic cyberpunk palette, hyper-detailed textures, 3D-rendered digital painting.
