各时代住宅的螺旋式构成

A spiral composition (not grid) with EXACTLY four concentric rings, each a photorealistic, ultra-realistic 12-K 3D-rendered miniature home cross-section with era-relevant elements. Rings: 1) 500 BC 2) 1000 AD 3) 1900 AD 4) 2025 AD. At 1 : 15 scale with intricate furnishings, lighting fixtures, and inhabitant silhouettes. On a rotating marble pedestal engraved with the four era labels exactly as written above ("500 BC 1000 AD 1900 AD 2025 AD", all-caps, correct spelling). Neutral gray walls curve subtly, with era windows glowing. Overhead light spirals inward, casting radial shadows for a motion illusion. Cinematic 16-K quality. Rings sit on a polished white-marble turntable. Neutral gray cyclorama background; single overhead spiral key-light casting radial shadows. Ultra-photoreal, cinematic quality, sharp textures. NEGATIVE PROMPT: MISSING_LABEL, MISSPELLED_TEXT, LOW_DETAIL, WRONG_RING_COUNT.
