Luxury Ribbed Suitcase Product Photo

Create a high-end studio product photograph of a premium hard-shell rolling suitcase in glossy gunmetal black, positioned on the right side of a wide horizontal frame with generous negative space on the left. The suitcase is a rigid aluminum-style carry-on with vertical ribbed grooves across the front, rounded reinforced black corner protectors, two visible side latches, a side handle, an extended telescoping pull handle, and exactly 4 double-spinner wheels visible near the base. Show it standing upright but slightly tilted back, photographed from a low three-quarter front angle so the front and right side are visible. Use dramatic luxury advertising lighting: dark charcoal-gray studio background, subtle vertical wall seam on the left, reflective black floor with soft reflections of the wheels and lower case, cool highlights along the ribs, controlled rim light, and a moody gradient backdrop. Keep the image photorealistic, sharp, premium, minimal, and cinematic, with no text, no logo, no people, and no clutter.
