A close-up engineering workshop scene where a focused mechanic adjusts components of a racing drone on her workbench as a floating AR-style diagram of the rotor mount assembling piece by piece. Her hands move with precise, deliberate motion as she tightens a bolt, metal tools clinking softly on the bench. The background remains softly blurred, filled with shelves of tools and scattered parts. Audio includes quiet mechanical hums, screwdrivers tapping, and subtle ventilation noise.
