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).
