Create a high-end commercial hero image of an unbranded compact portable espresso maker in matte graphite aluminum and clear borosilicate glass. Place it on a travertine slab with one espresso cup and a few roasted beans. Use dramatic diagonal morning light, crisp material definition, a natural steam plume and generous negative space without actual copy. Premium neutral palette, vertical 3:4 composition, no logos, no text, no watermark and no distorted product components.
