Minimalist Tech Poster on Aluminum Panel in Cyberpunk Lab with Drone Schematics

Ultra-minimalist tech poster mockup, A1 vertical format, blank matte gray poster area with sharp edges and subtle crumples, mounted on a brushed aluminum panel in a dim cyberpunk-style lab. The poster is surrounded by: faint holographic schematics of drone parts floating in air, slow-motion raindrops frozen in mid-air (gray color palette), low poly cityscape reflections on wet floor. Moody atmosphere with cold blue-tinged lighting, volumetric fog, and faint glow from LED strips on ceiling. The entire scene is desaturated (90% grayscale with 10% metallic blue accents), shot with shallow depth of field. Ultra-realistic Unreal Engine 5 rendering, 8K, no text or logos visible.
