Museum Exhibit: Odd Artifact

Create a photoreal museum display case containing an 'ancient artifact' that looks suspiciously like a sleek futuristic smartphone, but with worn edges, patina, and an inlaid geometric pattern. Include a small placard label with a short title and one sentence description (generic museum tone). Use soft gallery lighting, reflections on the glass, and a dark neutral background. The scene should feel believable and cinematic.
