Mechanical Metropolis: A City in a Book

Imagine a stunning isometric diorama where a mechanical city emerges from an open book, featuring intricate layers of porcelain and gold in a captivating clockwork design.

Prompt

Do this for tehran:  Input Variable:   [INSERT CITY OR LOCATION] (e.g., Mecca, London, Venice, The Shire, Cyberpunk City)

  System Instruction:  
Generate a hyper-detailed, isometric 3D diorama of a "Mechanical Metropolis" rising from an open book. Use the following logic to procedurally fill the scene with   Maximum Density  :

  1.  Urban :  
Analyze the Input Variable to extract   4 distinct layers of detail  :
      Layer A (The Skyline):   Identify the major architectural landmarks (e.g., The Kaaba, Big Ben, The Rialto Bridge).
      Layer B (The Transit):   Identify the specific method of movement.
         (e.g., Mecca = Flowing crowds of Pilgrims; London = Double Decker Buses; Venice = Gondolas). 
      Layer C (The Nature):   Identify the organic landscape features.
         (e.g., Desert Hills/Palms, The Thames River, Canals/Water). 
      Layer D (The Population):   Identify the tiny inhabitants (e.g., Worshippers, Businessmen in Bowlers, Hobbits).

  2. Container   
      The Object:   A massive, vintage   Hardcover Book   lying open flat.
      The Depth:   The pages are not just flat paper. They are   Excavated  . The book acts as a "foundation pit" where the mechanism is embedded deep into the chapters.

  3. The Material Palette  
  CRITICAL:   You must strictly adhere to this two-tone palette to maintain the aesthetic.
      The Architecture (White):   All buildings, ground, and nature must be rendered in   Pristine White Porcelain or Matte Alabaster  .
      The Mechanics (Gold):   All gears, cogs, chains, and typography must be   Polished Brass or 24k Gold  .
      The Contrast:   No other colors. Shadow and Reflection provide the contrast.

  4.  Diorama Construction 
      The Mechanism:   The gears should not just be decoration. They must appear to   Power the City  .
         Function:  Gold gears should be visible turning the wheels of the buses, creating the waves in the water, or rotating the circumambulation of the crowd.
      The Density:  
         Crowd Swarms:  Thousands of tiny   White Micro-Figures   (1:200 scale) fill the courtyards and streets. (e.g., The Tawaf circle in Mecca, or commuters on London Bridge).
         Vegetation:  Trees are made of stylized White Fractal Geometry or Gold Wire.

  5. The Typography:  
      Placement:   The Title stands vertically on the front edge of the book like a billboard, or lies flat in the foreground.
      Style:     3D Gold Calligraphy   (if Middle Eastern) or   Serif Block Letters   (if Western).
      Content:   The Name of the Location.

  6. Lighting & Atmosphere:  
      Lighting:     "Jewelry Store" Lighting.   Sharp, crisp white light that makes the gold sparkle and the white porcelain glow.
      Specularity:   High. The gold must reflect the white buildings.

  Output:   ONE image, 1:1 Aspect Ratio, Octane Render, "Clockwork" aesthetic, Intricate Micro-Detail.
