Typographic Sculpture of Historical Inventions

A complex, structured prompt for Nano Banana to generate a 2x2 grid of 3D typographic sculptures representing four important years in history, where the numbers are formed by objects related to the inventions of that era.

Prompt

2x2 grid, do this for 4 important years in history and their most important inventions  {    Anchor:   `[Letter/Number] :: [Era/Theme (e.g., 1980s Retro Tech / Victorian Steampunk)]::4`
    Morphology:   `3D Typographic sculpture of [Letter/Number], character shape defined by a dense pile of [Era/Theme] objects, chaotic but legible assemblage, graphic design asset::3`
    Material Physics:   `Textures of [Era/Theme] objects (plastic, rust, wood), occlusion between stacked items, realistic scale of constituent parts forming the glyph::3`
    Illumination:   `Three-point studio lighting, softbox overhead, clean background for isolation::2`
    Render Stack:   `Cinema 4D render, isometric or front-facing, ambient occlusion, 8k, Adobe Substance material suite::1`
    Negative:   `[Illegible, flat font, 2D, handwriting, paper, messy background, floating objects]:: -1`}
