<instructions>
Input Variable: [City/Year A vs. City/Year B] (e.g., New York 1900 vs. New York 2025)

System Instruction:
Generate a photorealistic, isometric macro render of a split-era urban diorama. The goal is Historical and Municipal Accuracy, avoiding sci-fi tropes or idealization.

1. Temporal Forensic Analysis:
Analyze the Dates:
 Strictly adhere to the architectural technologies available in Year A versus Year B.
The Left Block (The Past): Construct the Left side using the dominant vernacular of the era.
For 1900: Beaux-Arts stone, brick tenements, water towers, external fire escapes, and cobblestone/early asphalt.
The Right Block (The Present/Future): Construct the Right side using current urban realities, not futuristic fantasies.
For 2025: Prioritize "Super-Slender" Pencil Towers (Billionaire's Row style), Glass Curtain Walls mixed with preserved older facades, and "Hudson Yards" style angled steel.
 Crucial Detail: If the year is modern (2020+), you MUST include Urban Clutter: Green construction plywood barriers, sidewalk scaffolding (sheds), steam vents, and delivery trucks.

2. The Container (The Cross-Section):
The Base: Two suspended chunks of city infrastructure, revealing the "Underground" layer on the side profile.
Left Underground: Brick sewers and early subway tunnels.
Right Underground: Concrete conduit banks, fiber optic lines, and modern subway tiles.
The Divider: A jagged timeline fracture. No glowing sci-fi energy. The divide is a stark cut in the asphalt.

3. The Composition (The Density):
Left Street Life: Period-accurate transport (Horse-drawn carriages mixed with early Model T Fords or Trolleys). Pedestrians in dark coats/hats.
Right Street Life: Municipal Realism. Yellow Taxis, Amazon delivery vans, Uber cars, and bike lanes with cyclists. The street level should feel congested and chaotic.
Vegetation: Left has Elm trees (if applicable); Right has manicured "Corporate Plaza" planters and rooftop gardens.

4. Accurate Lighting Simulation (No "Neon Filters"):
Left Lighting: Carbon-Arc and Gaslight. The light should be dim, patchy, and warm (2400K), casting long shadows.
 Right Lighting: Mixed Municipal Lighting. A chaotic mix of warm sodium streetlights (orange), harsh white LED construction lights (6000K), and internal office lighting (neutral). Do not use "Cyberpunk Blue" or "Purple" unless it is a specific billboard.
Atmosphere: The Left is hazy from coal smoke. The Right has a clearer, sharper air quality but with light pollution.

5. Visual Syntax:
Camera: Isometric Orthographic projection, 45-degree angle.
Render Style: Photorealistic Architectural Visualization (ArchViz), 8k, V-Ray Render. Focus on texture fidelity (rust, wet pavement, grime) rather than bloom effects.

Output: 1:1 Aspect Ratio, Extreme Detail, Historically Authentic.
