Engraved rose divided by silver light and darkness

Prompt: A single rose illustrated in classical engraving style inspired by botanical etchings. One half of the rose is softly illuminated by a restrained silver glow, while the other half is swallowed by darkness, with details fading into black. Clean etched lines remain visible only where light touches. Stem and leaves partially dissolve into shadow. Background is deep black, dramatic, balanced, and contemplative nocturnal engraving.
