2x2 Grid of Four Generations with GPT Image

2x2 grid, 16:9, do this for 4 different generations and their traits, lifestyle (e.g. Boomers, Gen Z, ...) I(0) = blank matte void. I(1) = final nested set of transparent isometric shells for $ THEME, each shell one zoom level larger than the last, the outermost shell profiled as silhouette $ SHAPE. ∂I/∂t = Δ(I, $ THEME, $ SHAPE) with constraints: isometric projection, inner‑to‑outer scale progression, cross‑shell subject continuity, glass‑shell transparency gradient, soft volumetric light. Integration: t=0.0–0.15: faint silhouette outline of the outer shell and concentric shell guides appear. t=0.15–0.4: the innermost shell renders first at the core - the smallest scale of $ THEME, densely detailed, fully opaque. t=0.4–0.7: each surrounding shell nests outward, one step up in scale, growing more transparent so inner shells stay visible through them. t=0.7–0.9: the outermost shell (largest scale) closes around the rest, completing the silhouette as a faint glass boundary. t=0.9–1.0: volumetric light settles between shells, scale labels appear on a radial line piercing all shells, final polish. Output I(1) as an 8K nested‑scale masterwork.
