Create a luxury industrial-design material study of a palm-sized mechanical hummingbird, isolated in three-quarter profile on a warm neutral studio plinth. Its outer shell is translucent cobalt-blue blown glass with visible copper filigree joints; keep an anatomically coherent hummingbird silhouette, fine articulated wings, beak, and compact mechanics. Show physically accurate refraction, copper edge highlights, and one small amber light in the chest. Premium macro product photography, softbox key, dark navy gradient background. No labels, text, logos, or collage.
