Create:
1. A finished retro futurism prompt consistent with the selected era and practical purpose.
2. Optimistic and uneasy variations that preserve the same technology.
3. A close product or interface view without fake text.
4. A negative prompt for mixed decades, generic cyberpunk clutter, copied spacecraft, impossible controls, logos, and watermarks.
5. Notes on era cues, technology logic, scale, palette, and silhouette.
6. An originality check against recognizable franchises, products, and published artwork.

Make the future feel designed by people from the selected period, not merely covered in vintage color grading.
