Time Capsule Dioramas Gemini Nano Banana Pro Prompt: Create a clear, 45° top-down isometric miniature 3D diorama representing the era [YEAR / DECADE] as a time capsule. Use soft refined textures, realistic PBR materials, and gentle nostalgic lighting. Design a raised base filled with iconic objects, fashion, technology, and cultural symbols from this era. Include tiny stylized people interacting with the environment (no facial details). Use a clean solid [BACKGROUND COLOR] background. At the top-center, display [ERA NAME] in large bold text, beneath it show a short nostalgic subtitle, and place a minimal retro-style icon below. All text must automatically match the background contrast (white or black).
